19512 divided by 57 
The aim is to understand the frequency of 57 in 19512.

Advancing to step 1:
When dividing 1 by 57, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 57

On to step 2:
57 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 57

Moving on to step 3:
57 can be fit into 195 3 times, resulting in a remainder of 24.
The next digit of our result is 3. 
Result so far: 3.0
If we take 171 away from 195, we end up with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 57

Moving on to step 4:
57 can be fit into 241 4 times, resulting in a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 228 from 241 and we're left with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 57

Going ahead to step 5:
When dividing 132 by 57, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
If we subtract 114 from 132, we 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.

Moving on to step 6:
57 can be fit into 180 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 342.3
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.

Going ahead to step 7:
The number 57 fits into 90 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 342.31
Subtracting 57 from 90 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
57 goes into 330 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 342.315
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.

Moving on to step 9:
450 divided by 57 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 342.3157
If we take 399 away from 450, we end up with 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 10:
If we divide 510 by 57, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 342.31578
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 11:
540 divided by 57 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 342.315789
Subtracting 513 from 540 leaves us 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.

Advancing to step 12:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 342.3157894
If we subtract 228 from 270, we 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.

Moving on to step 13:
The number 57 fits into 420 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 342.31578947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 342.31578947 with a remainder of 2.1e-08.
