We're dividing 42127 by 57 
Our goal is to divide 42127 by 57.

Step 1:
4 divided by 57 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 57

Let's proceed to step 2:
42 divided by 57 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 57

Step 3:
If we divide 421 by 57, we get 7 and a remainder of 22.
The next digit of our result is 7. 
Result so far: 7.0
If we take 399 away from 421, we end up with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 57

Advancing to step 4:
222 divided by 57 is 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 171 from 222 and we're left with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 57

Advancing to step 5:
57 goes into 517 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 739.0
Subtract 513 from 517 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 6:
If we divide 40 by 57, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 739.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
400 divided by 57 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 739.07
If we subtract 399 from 400, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 57 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 739.07
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
57 goes into 100 1 times with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 739.0701
Subtract 57 from 100 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
If we divide 430 by 57, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 739.07017
Subtract 399 from 430 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
57 goes into 310 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 739.070175
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
The number 57 fits into 250 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 739.0701754
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
The number 57 fits into 220 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 739.07017543
Subtracting 171 from 220 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 739.07017543, with a leftover of 4.9e-08.
