We divide 89725574 by 528
The aim is to understand the frequency of 528 in 89725574.

Moving on to step 1:
If we divide 8 by 528, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 528

Let's proceed to step 2:
The number 528 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 528

On to step 3:
528 can be fit into 897 1 times, resulting in a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 528 from 897 to get 369.
Bring next digit (2) of the dividend behind the 369 and repeat the process: 3692 / 528

On to step 4:
When dividing 3692 by 528, we get 6 with a remainder of 524.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 3168 away from 3692, we end up with 524.
Append the next digit (5) from the dividend to 524 and continue with: 5245 / 528

Advancing to step 5:
5245 divided by 528 is 9 with a remainder of 493.
Use 9 as the next digit of our solution. 
Result so far: 169.0
The remainder is 493 after subtracting 4752 from 5245.
Append the next digit (5) from the dividend to 493 and continue with: 4935 / 528

Let's proceed to step 6:
4935 divided by 528 is 9 with a remainder of 183.
The next digit of our result is 9. 
Result so far: 1699.0
If we subtract 4752 from 4935, we get 183.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 528

Going ahead to step 7:
If we divide 1837 by 528, we get 3 and a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 16993.0
Deduct 1584 from 1837 and we're left with 253.
Append the next digit (4) from the dividend to 253 and continue with: 2534 / 528

Going ahead to step 8:
528 can be fit into 2534 4 times, resulting in a remainder of 422.
The number 4 becomes the next digit in our result. 
Result so far: 169934.0
Deduct 2112 from 2534 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 9:
4220 divided by 528 is 7 with a remainder of 524.
Put 7 as the next digit of the answer. 
Result so far: 169934.7
The remainder is 524 after subtracting 3696 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 10:
The number 528 fits into 5240 9 times, leaving a remainder of 488.
Use 9 as the next digit of our solution. 
Result so far: 169934.79
If we subtract 4752 from 5240, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 11:
If we divide 4880 by 528, we get 9 and a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 169934.799
Deduct 4752 from 4880 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 169934.799 with a remainder of 0.0128.
