We look at the division of 396296 by 57 
The aim is to understand the frequency of 57 in 396296.

On to step 1:
3 divided by 57 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 57

Advancing to step 2:
57 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 57

On to step 3:
396 divided by 57 is 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 342 from 396, we get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 57

On to step 4:
The number 57 fits into 542 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 513 from 542 leaves us with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 57

Step 5:
When dividing 299 by 57, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 695.0
If we take 285 away from 299, we end up with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 57

Step 6:
146 divided by 57 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 6952.0
Subtract 114 from 146 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
If we divide 320 by 57, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 6952.5
Subtracting 285 from 320 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
When dividing 350 by 57, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6952.56
If we subtract 342 from 350, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
57 goes into 80 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 6952.561
The remainder is 23 after subtracting 57 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
230 divided by 57 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 6952.5614
If we subtract 228 from 230, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
When dividing 20 by 57, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6952.5614
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 57, we get 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 6952.561403
Subtracting 171 from 200 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
57 can be fit into 290 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6952.5614035
Deduct 285 from 290 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
If we divide 50 by 57, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 6952.5614035
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 6952.5614035 and a remainder of 5e-08.
