Let's divide 312980 by 57
The aim is to understand the frequency of 57 in 312980.

Advancing to step 1:
3 divided by 57 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 57

Advancing to step 2:
If we divide 31 by 57, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 57

On to step 3:
312 divided by 57 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 285 from 312 to get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 57

Step 4:
If we divide 279 by 57, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 51 after subtracting 228 from 279.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 57

Moving on to step 5:
57 goes into 518 9 times with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 549.0
Subtract 513 from 518 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 57

On to step 6:
57 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 5490.0
Subtracting 0 from 50 leaves us 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.

Let's proceed to step 7:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 5490.8
Subtract 456 from 500 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
57 goes into 440 7 times with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 5490.87
Subtract 399 from 440 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
410 divided by 57 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 5490.877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 5490.877 with a balance of 0.0011.
