Let's divide 127543 by 57
The aim is to understand the frequency of 57 in 127543.

On to step 1:
57 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 57

Advancing to step 2:
If we divide 12 by 57, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 57

Moving on to step 3:
57 goes into 127 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 114 from 127 leaves us with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 57

On to step 4:
57 goes into 135 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 114 from 135 leaves us with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 57

Step 5:
The number 57 fits into 214 3 times, leaving a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 223.0
If we subtract 171 from 214, we get 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 57

Step 6:
57 goes into 433 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 2237.0
Subtracting 399 from 433 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
340 divided by 57 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 2237.5
Subtracting 285 from 340 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
The number 57 fits into 550 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 2237.59
If we subtract 513 from 550, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
The number 57 fits into 370 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 2237.596
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
280 divided by 57 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 2237.5964
Deduct 228 from 280 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
The number 57 fits into 520 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 2237.59649
If we take 513 away from 520, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
When dividing 70 by 57, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 2237.596491
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
57 goes into 130 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2237.5964912
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
160 divided by 57 is 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 2237.59649122
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 2237.59649122, with a leftover of 4.6e-08.
