We look at the division of 87502569 by 532 
The aim is to understand the frequency of 532 in 87502569.

Going ahead to step 1:
The number 532 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 532

Advancing to step 2:
If we divide 87 by 532, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (5) of the dividend behind the 87 and repeat the process: 875 / 532

Advancing to step 3:
When dividing 875 by 532, we get 1 with a remainder of 343.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 532 away from 875, we end up with 343.
Include the next digit (0) from the dividend after 343, then repeat: 3430 / 532

Advancing to step 4:
If we divide 3430 by 532, we get 6 and a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 238 after subtracting 3192 from 3430.
Grab the next digit (2) from the dividend, add it to 238, then carry on: 2382 / 532

On to step 5:
If we divide 2382 by 532, we get 4 and a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Deduct 2128 from 2382 and we're left with 254.
Append the next digit (5) from the dividend to 254 and continue with: 2545 / 532

Let's proceed to step 6:
532 goes into 2545 4 times with a remainder of 417.
Put 4 as the next digit of the answer. 
Result so far: 1644.0
Deduct 2128 from 2545 and we're left with 417.
Bring next digit (6) of the dividend behind the 417 and repeat the process: 4176 / 532

Going ahead to step 7:
532 can be fit into 4176 7 times, resulting in a remainder of 452.
Put 7 as the next digit of the answer. 
Result so far: 16447.0
The remainder is 452 after subtracting 3724 from 4176.
Bring next digit (9) of the dividend behind the 452 and repeat the process: 4529 / 532

Moving on to step 8:
532 can be fit into 4529 8 times, resulting in a remainder of 273.
Write down 8 as next digit of the result. 
Result so far: 164478.0
Deduct 4256 from 4529 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 9:
532 can be fit into 2730 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 164478.5
If we take 2660 away from 2730, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
When dividing 700 by 532, we get 1 with a remainder of 168.
Record the quotient 1 as the next digit in the result. 
Result so far: 164478.51
If we take 532 away from 700, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 11:
532 goes into 1680 3 times with a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 164478.513
The remainder is 84 after subtracting 1596 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
The number 532 fits into 840 1 times, leaving a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 164478.5131
Subtract 532 from 840 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 13:
The number 532 fits into 3080 5 times, leaving a remainder of 420.
Put 5 as the next digit of the answer. 
Result so far: 164478.51315
The remainder is 420 after subtracting 2660 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
4200 divided by 532 is 7 with a remainder of 476.
The next digit of our result is 7. 
Result so far: 164478.513157
Subtracting 3724 from 4200 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 15:
If we divide 4760 by 532, we get 8 and a remainder of 504.
The number 8 becomes the next digit in our result. 
Result so far: 164478.5131578
The remainder is 504 after subtracting 4256 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 16:
When dividing 5040 by 532, we get 9 with a remainder of 252.
The next digit of our result is 9. 
Result so far: 164478.51315789
The remainder is 252 after subtracting 4788 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 164478.51315789 and a remainder of 2.52e-07.
