83128160 ÷ 657 
The aim is to understand the frequency of 657 in 83128160.

Moving on to step 1:
The number 657 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 657

Step 2:
When dividing 83 by 657, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 657

On to step 3:
831 divided by 657 is 1 with a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 657 from 831 to get 174.
Include the next digit (2) from the dividend after 174, then repeat: 1742 / 657

On to step 4:
If we divide 1742 by 657, we get 2 and a remainder of 428.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1314 away from 1742, we end up with 428.
Fetch the next digit (8) from the dividend, attach it to 428 and continue: 4288 / 657

Step 5:
4288 divided by 657 is 6 with a remainder of 346.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 3942 from 4288 to get 346.
Append the next digit (1) from the dividend to 346 and continue with: 3461 / 657

Advancing to step 6:
If we divide 3461 by 657, we get 5 and a remainder of 176.
Use 5 as the next digit of our solution. 
Result so far: 1265.0
Deduct 3285 from 3461 and we're left with 176.
Append the next digit (6) from the dividend to 176 and continue with: 1766 / 657

Going ahead to step 7:
657 can be fit into 1766 2 times, resulting in a remainder of 452.
Use 2 as the next digit of our solution. 
Result so far: 12652.0
Subtract 1314 from 1766 to get 452.
Include the next digit (0) from the dividend after 452, then repeat: 4520 / 657

On to step 8:
When dividing 4520 by 657, we get 6 with a remainder of 578.
Record the quotient 6 as the next digit in the result. 
Result so far: 126526.0
Subtracting 3942 from 4520 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 9:
657 goes into 5780 8 times with a remainder of 524.
The next digit of our result is 8. 
Result so far: 126526.8
The remainder is 524 after subtracting 5256 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 10:
657 can be fit into 5240 7 times, resulting in a remainder of 641.
The next digit of our result is 7. 
Result so far: 126526.87
If we subtract 4599 from 5240, we get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Step 11:
If we divide 6410 by 657, we get 9 and a remainder of 497.
Put 9 as the next digit of the answer. 
Result so far: 126526.879
Deduct 5913 from 6410 and we're left with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 12:
657 can be fit into 4970 7 times, resulting in a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 126526.8797
Subtract 4599 from 4970 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 13:
The number 657 fits into 3710 5 times, leaving a remainder of 425.
The next digit of our result is 5. 
Result so far: 126526.87975
Deduct 3285 from 3710 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 14:
When dividing 4250 by 657, we get 6 with a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 126526.879756
If we subtract 3942 from 4250, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 15:
657 goes into 3080 4 times with a remainder of 452.
Use 4 as the next digit of our solution. 
Result so far: 126526.8797564
Subtract 2628 from 3080 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 16:
When dividing 4520 by 657, we get 6 with a remainder of 578.
Record the quotient 6 as the next digit in the result. 
Result so far: 126526.87975646
If we subtract 3942 from 4520, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The final outcome is 126526.87975646, with a leftover of 5.78e-07.
