We're dividing 88139728 by 529 
The aim is to understand the frequency of 529 in 88139728.

On to step 1:
8 divided by 529 is 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.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 529

Going ahead to step 2:
If we divide 88 by 529, we get 0 and a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Grab the next digit (1) from the dividend, add it to 88, then carry on: 881 / 529

Going ahead to step 3:
881 divided by 529 is 1 with a remainder of 352.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 529 from 881, we get 352.
Grab the next digit (3) from the dividend, add it to 352, then carry on: 3523 / 529

Advancing to step 4:
The number 529 fits into 3523 6 times, leaving a remainder of 349.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 3174 from 3523 to get 349.
Bring next digit (9) of the dividend behind the 349 and repeat the process: 3499 / 529

Step 5:
529 goes into 3499 6 times with a remainder of 325.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 3174 from 3499, we get 325.
Bring next digit (7) of the dividend behind the 325 and repeat the process: 3257 / 529

On to step 6:
If we divide 3257 by 529, we get 6 and a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 1666.0
Subtracting 3174 from 3257 leaves us with 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 529

On to step 7:
832 divided by 529 is 1 with a remainder of 303.
Record the quotient 1 as the next digit in the result. 
Result so far: 16661.0
If we subtract 529 from 832, we get 303.
Fetch the next digit (8) from the dividend, attach it to 303 and continue: 3038 / 529

Going ahead to step 8:
The number 529 fits into 3038 5 times, leaving a remainder of 393.
The next digit of our result is 5. 
Result so far: 166615.0
If we take 2645 away from 3038, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 9:
529 goes into 3930 7 times with a remainder of 227.
Record the quotient 7 as the next digit in the result. 
Result so far: 166615.7
Subtract 3703 from 3930 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 10:
When dividing 2270 by 529, we get 4 with a remainder of 154.
Put 4 as the next digit of the answer. 
Result so far: 166615.74
Subtract 2116 from 2270 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 11:
The number 529 fits into 1540 2 times, leaving a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 166615.742
If we take 1058 away from 1540, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 12:
When dividing 4820 by 529, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 166615.7429
The remainder is 59 after subtracting 4761 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 13:
When dividing 590 by 529, we get 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 166615.74291
If we subtract 529 from 590, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
610 divided by 529 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 166615.742911
Deduct 529 from 610 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 166615.742911, with a leftover of 8.1e-06.
