Let's divide 90627885 by 527
The aim is to understand the frequency of 527 in 90627885.

On to step 1:
The number 527 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 527

Moving on to step 2:
The number 527 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 527

Advancing to step 3:
If we divide 906 by 527, we get 1 and a remainder of 379.
The next digit of our result is 1. 
Result so far: 1.0
If we take 527 away from 906, we end up with 379.
Append the next digit (2) from the dividend to 379 and continue with: 3792 / 527

Moving on to step 4:
When dividing 3792 by 527, we get 7 with a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 3689 from 3792, we get 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 527

Advancing to step 5:
The number 527 fits into 1037 1 times, leaving a remainder of 510.
Use 1 as the next digit of our solution. 
Result so far: 171.0
The remainder is 510 after subtracting 527 from 1037.
Bring next digit (8) of the dividend behind the 510 and repeat the process: 5108 / 527

Moving on to step 6:
The number 527 fits into 5108 9 times, leaving a remainder of 365.
Record the quotient 9 as the next digit in the result. 
Result so far: 1719.0
Subtract 4743 from 5108 to get 365.
Fetch the next digit (8) from the dividend, attach it to 365 and continue: 3658 / 527

Step 7:
The number 527 fits into 3658 6 times, leaving a remainder of 496.
The next digit of our result is 6. 
Result so far: 17196.0
Deduct 3162 from 3658 and we're left with 496.
Fetch the next digit (5) from the dividend, attach it to 496 and continue: 4965 / 527

Moving on to step 8:
If we divide 4965 by 527, we get 9 and a remainder of 222.
Put 9 as the next digit of the answer. 
Result so far: 171969.0
If we take 4743 away from 4965, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 9:
527 goes into 2220 4 times with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 171969.4
Subtract 2108 from 2220 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
When dividing 1120 by 527, we get 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 171969.42
If we take 1054 away from 1120, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
527 can be fit into 660 1 times, resulting in a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 171969.421
Subtracting 527 from 660 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 12:
527 goes into 1330 2 times with a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 171969.4212
If we take 1054 away from 1330, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 13:
The number 527 fits into 2760 5 times, leaving a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 171969.42125
Subtract 2635 from 2760 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 14:
The number 527 fits into 1250 2 times, leaving a remainder of 196.
The next digit of our result is 2. 
Result so far: 171969.421252
If we take 1054 away from 1250, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 15:
If we divide 1960 by 527, we get 3 and a remainder of 379.
The next digit of our result is 3. 
Result so far: 171969.4212523
The remainder is 379 after subtracting 1581 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 16:
If we divide 3790 by 527, we get 7 and a remainder of 101.
Record the quotient 7 as the next digit in the result. 
Result so far: 171969.42125237
Deduct 3689 from 3790 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 171969.42125237, with a leftover of 1.01e-07.
