Let's divide 86687332 by 528
The aim is to understand the frequency of 528 in 86687332.

Moving on to step 1:
528 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 528

Let's proceed to step 2:
86 divided by 528 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 528

Going ahead to step 3:
528 can be fit into 866 1 times, resulting in a remainder of 338.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 528 from 866 and we're left with 338.
Append the next digit (8) from the dividend to 338 and continue with: 3388 / 528

Going ahead to step 4:
If we divide 3388 by 528, we get 6 and a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 3168 from 3388, we get 220.
Fetch the next digit (7) from the dividend, attach it to 220 and continue: 2207 / 528

Going ahead to step 5:
2207 divided by 528 is 4 with a remainder of 95.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtracting 2112 from 2207 leaves us with 95.
Fetch the next digit (3) from the dividend, attach it to 95 and continue: 953 / 528

Moving on to step 6:
528 can be fit into 953 1 times, resulting in a remainder of 425.
The next digit of our result is 1. 
Result so far: 1641.0
Subtract 528 from 953 to get 425.
Fetch the next digit (3) from the dividend, attach it to 425 and continue: 4253 / 528

Advancing to step 7:
528 can be fit into 4253 8 times, resulting in a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 16418.0
The remainder is 29 after subtracting 4224 from 4253.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 528

Moving on to step 8:
528 can be fit into 292 0 times, resulting in a remainder of 292.
Use 0 as the next digit of our solution. 
Result so far: 164180.0
The remainder is 292 after subtracting 0 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 9:
The number 528 fits into 2920 5 times, leaving a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 164180.5
Subtracting 2640 from 2920 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
528 can be fit into 2800 5 times, resulting in a remainder of 160.
The next digit of our result is 5. 
Result so far: 164180.55
Deduct 2640 from 2800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 164180.55, with a leftover of 0.16.
