We're dividing 57980441 by 657 
The aim is to understand the frequency of 657 in 57980441.

Step 1:
When dividing 5 by 657, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 657

Going ahead to step 2:
If we divide 57 by 657, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 657

Advancing to step 3:
657 can be fit into 579 0 times, resulting in a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 579 after subtracting 0 from 579.
Append the next digit (8) from the dividend to 579 and continue with: 5798 / 657

Moving on to step 4:
657 goes into 5798 8 times with a remainder of 542.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5256 from 5798 and we're left with 542.
Bring next digit (0) of the dividend behind the 542 and repeat the process: 5420 / 657

Going ahead to step 5:
The number 657 fits into 5420 8 times, leaving a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 5256 from 5420 leaves us with 164.
Append the next digit (4) from the dividend to 164 and continue with: 1644 / 657

Let's proceed to step 6:
1644 divided by 657 is 2 with a remainder of 330.
The number 2 becomes the next digit in our result. 
Result so far: 882.0
Deduct 1314 from 1644 and we're left with 330.
Include the next digit (4) from the dividend after 330, then repeat: 3304 / 657

On to step 7:
The number 657 fits into 3304 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 8825.0
If we take 3285 away from 3304, we end up with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 657

Advancing to step 8:
The number 657 fits into 191 0 times, leaving a remainder of 191.
Put 0 as the next digit of the answer. 
Result so far: 88250.0
Subtracting 0 from 191 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 9:
When dividing 1910 by 657, we get 2 with a remainder of 596.
Write down 2 as next digit of the result. 
Result so far: 88250.2
Subtracting 1314 from 1910 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 10:
When dividing 5960 by 657, we get 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 88250.29
If we subtract 5913 from 5960, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
If we divide 470 by 657, we get 0 and a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 88250.29
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 12:
The number 657 fits into 4700 7 times, leaving a remainder of 101.
Record the quotient 7 as the next digit in the result. 
Result so far: 88250.2907
Subtract 4599 from 4700 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 13:
657 can be fit into 1010 1 times, resulting in a remainder of 353.
Write down 1 as next digit of the result. 
Result so far: 88250.29071
Subtract 657 from 1010 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 14:
3530 divided by 657 is 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 88250.290715
Deduct 3285 from 3530 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 15:
657 can be fit into 2450 3 times, resulting in a remainder of 479.
Use 3 as the next digit of our solution. 
Result so far: 88250.2907153
If we take 1971 away from 2450, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 16:
If we divide 4790 by 657, we get 7 and a remainder of 191.
Record the quotient 7 as the next digit in the result. 
Result so far: 88250.29071537
Subtracting 4599 from 4790 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

In conclusion, the division gives 88250.29071537 with a balance of 1.91e-07.
