We look at the division of 752772 by 57 
The aim is to understand the frequency of 57 in 752772.

Step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 57

Advancing to step 2:
The number 57 fits into 75 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 57 from 75 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 57

On to step 3:
If we divide 182 by 57, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 171 away from 182, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 57

Moving on to step 4:
57 goes into 117 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 132.0
Subtract 114 from 117 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 57

Step 5:
57 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 1320.0
If we subtract 0 from 37, we get 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 57

Let's proceed to step 6:
57 goes into 372 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 13206.0
Subtract 342 from 372 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13206.5
If we subtract 285 from 300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
57 can be fit into 150 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 13206.52
The remainder is 36 after subtracting 114 from 150.
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 9:
The number 57 fits into 360 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 13206.526
The remainder is 18 after subtracting 342 from 360.
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 10:
When dividing 180 by 57, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13206.5263
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.

Going ahead to step 11:
The number 57 fits into 90 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 13206.52631
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 12:
If we divide 330 by 57, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 13206.526315
If we take 285 away from 330, we end up 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.

Step 13:
When dividing 450 by 57, we get 7 with a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 13206.5263157
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.

On to step 14:
57 goes into 510 8 times with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 13206.52631578
If we subtract 456 from 510, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 13206.52631578 with a balance of 5.4e-08.
