We look at the division of 127421 by 57 
We want to figure out the number of times 127421 can be divided by 57.

On to step 1:
The number 57 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 57

Going ahead to step 2:
57 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 57

Going ahead to step 3:
57 can be fit into 127 2 times, resulting in 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.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 57

Advancing to step 4:
57 can be fit into 134 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 114 from 134 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 57

Moving on to step 5:
57 can be fit into 202 3 times, resulting in a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 223.0
Deduct 171 from 202 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 57

Step 6:
When dividing 311 by 57, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 2235.0
If we subtract 285 from 311, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 57, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 2235.4
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
57 goes into 320 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2235.45
Subtract 285 from 320 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
350 divided by 57 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 2235.456
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 57, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 2235.4561
The remainder is 23 after subtracting 57 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
57 goes into 230 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 2235.45614
If we take 228 away from 230, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
When dividing 20 by 57, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2235.45614
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
57 goes into 200 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 2235.4561403
Subtract 171 from 200 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 14:
290 divided by 57 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2235.45614035
Subtract 285 from 290 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 2235.45614035, and the remainder is 5e-09.
