We look at the division of 76868 by 57 
The aim is to understand the frequency of 57 in 76868.

Step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 57

Advancing to step 2:
57 goes into 76 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 57 from 76 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 57

Advancing to step 3:
198 divided by 57 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 27 after subtracting 171 from 198.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 57

Going ahead to step 4:
The number 57 fits into 276 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 134.0
The remainder is 48 after subtracting 228 from 276.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 57

Going ahead to step 5:
488 divided by 57 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 1348.0
Deduct 456 from 488 and we're left with 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 6:
When dividing 320 by 57, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1348.5
Subtract 285 from 320 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
57 goes into 350 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1348.56
Deduct 342 from 350 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
57 can be fit into 80 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1348.561
Subtracting 57 from 80 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
If we divide 230 by 57, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1348.5614
Deduct 228 from 230 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
57 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1348.5614
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
The number 57 fits into 200 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 1348.561403
Subtract 171 from 200 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
290 divided by 57 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1348.5614035
If we take 285 away from 290, we end up 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.

Going ahead to step 13:
57 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1348.5614035
Subtract 0 from 50 to get 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 1348.5614035 and a remainder of 5e-08.
