We look at the division of 625932 by 57 
The aim is to understand the frequency of 57 in 625932.

Step 1:
6 divided by 57 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 57

Let's proceed to step 2:
If we divide 62 by 57, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 62 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 57

Let's proceed to step 3:
55 divided by 57 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 55, we get 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 57

Going ahead to step 4:
559 divided by 57 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtracting 513 from 559 leaves us with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 57

On to step 5:
When dividing 463 by 57, we get 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 1098.0
Subtract 456 from 463 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 57

Advancing to step 6:
57 goes into 72 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 10981.0
Deduct 57 from 72 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
57 can be fit into 150 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 10981.2
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 57, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 10981.26
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
57 goes into 180 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 10981.263
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
90 divided by 57 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 10981.2631
The remainder is 33 after subtracting 57 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
57 can be fit into 330 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 10981.26315
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
When dividing 450 by 57, we get 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 10981.263157
Subtract 399 from 450 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 10981.2631578
The remainder is 54 after subtracting 456 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
540 divided by 57 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 10981.26315789
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 10981.26315789 with a remaining 2.7e-08.
