Let's divide 87580165 by 574
The aim is to understand the frequency of 574 in 87580165.

Let's proceed to step 1:
When dividing 8 by 574, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 574

Advancing to step 2:
574 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (5) from the dividend after 87, then repeat: 875 / 574

Going ahead to step 3:
When dividing 875 by 574, we get 1 with a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 574 from 875 and we're left with 301.
Append the next digit (8) from the dividend to 301 and continue with: 3018 / 574

Going ahead to step 4:
The number 574 fits into 3018 5 times, leaving a remainder of 148.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2870 from 3018 and we're left with 148.
Append the next digit (0) from the dividend to 148 and continue with: 1480 / 574

Step 5:
574 goes into 1480 2 times with a remainder of 332.
Write down 2 as next digit of the result. 
Result so far: 152.0
Deduct 1148 from 1480 and we're left with 332.
Include the next digit (1) from the dividend after 332, then repeat: 3321 / 574

Moving on to step 6:
574 goes into 3321 5 times with a remainder of 451.
Record the quotient 5 as the next digit in the result. 
Result so far: 1525.0
If we subtract 2870 from 3321, we get 451.
Grab the next digit (6) from the dividend, add it to 451, then carry on: 4516 / 574

On to step 7:
When dividing 4516 by 574, we get 7 with a remainder of 498.
Write down 7 as next digit of the result. 
Result so far: 15257.0
The remainder is 498 after subtracting 4018 from 4516.
Bring next digit (5) of the dividend behind the 498 and repeat the process: 4985 / 574

Step 8:
4985 divided by 574 is 8 with a remainder of 393.
Put 8 as the next digit of the answer. 
Result so far: 152578.0
The remainder is 393 after subtracting 4592 from 4985.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 9:
574 goes into 3930 6 times with a remainder of 486.
The next digit of our result is 6. 
Result so far: 152578.6
Subtract 3444 from 3930 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 10:
574 goes into 4860 8 times with a remainder of 268.
The next digit of our result is 8. 
Result so far: 152578.68
The remainder is 268 after subtracting 4592 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 11:
574 can be fit into 2680 4 times, resulting in a remainder of 384.
The next digit of our result is 4. 
Result so far: 152578.684
The remainder is 384 after subtracting 2296 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 574, we get 6 with a remainder of 396.
The next digit of our result is 6. 
Result so far: 152578.6846
If we subtract 3444 from 3840, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 13:
When dividing 3960 by 574, we get 6 with a remainder of 516.
The next digit of our result is 6. 
Result so far: 152578.68466
The remainder is 516 after subtracting 3444 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

The quotient of the division is 152578.68466, and the remainder is 0.000516.
