We look at the division of 331776 by 57 
The aim is to understand the frequency of 57 in 331776.

Let's proceed to step 1:
3 divided by 57 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 57

Advancing to step 2:
When dividing 33 by 57, we get 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 57

Advancing to step 3:
When dividing 331 by 57, we get 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 5.0
If we take 285 away from 331, we end up with 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 57

Advancing to step 4:
If we divide 467 by 57, we get 8 and a remainder of 11.
The next digit of our result is 8. 
Result so far: 58.0
Subtracting 456 from 467 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 57

Moving on to step 5:
117 divided by 57 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 582.0
If we subtract 114 from 117, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 57

On to step 6:
When dividing 36 by 57, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 5820.0
Subtract 0 from 36 to get 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 7:
57 goes into 360 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 5820.6
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 57 fits into 180 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 5820.63
If we take 171 away from 180, we end up 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 9:
57 can be fit into 90 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 5820.631
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.

Step 10:
330 divided by 57 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5820.6315
Subtracting 285 from 330 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
If we divide 450 by 57, we get 7 and a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 5820.63157
If we subtract 399 from 450, we 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.

Going ahead to step 12:
If we divide 510 by 57, we get 8 and a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 5820.631578
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.

Moving on to step 13:
540 divided by 57 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 5820.6315789
Deduct 513 from 540 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
57 can be fit into 270 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 5820.63157894
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 5820.63157894, and the remainder is 4.2e-08.
