Let's divide 124140 by 57
Let's see how many times 57 fits into 124140.

Step 1:
57 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 57

Step 2:
The number 57 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 57

Step 3:
124 divided by 57 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 10 after subtracting 114 from 124.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 57

Going ahead to step 4:
The number 57 fits into 101 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 57 from 101, we get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 57

Going ahead to step 5:
57 can be fit into 444 7 times, resulting in a remainder of 45.
The next digit of our result is 7. 
Result so far: 217.0
The remainder is 45 after subtracting 399 from 444.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 57

Advancing to step 6:
The number 57 fits into 450 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 2177.0
Subtract 399 from 450 to 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.

Going ahead to step 7:
If we divide 510 by 57, we get 8 and a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 2177.8
Subtract 456 from 510 to 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.

On to step 8:
57 goes into 540 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 2177.89
The remainder is 27 after subtracting 513 from 540.
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 9:
270 divided by 57 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 2177.894
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 57, we get 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 2177.8947
Subtracting 399 from 420 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
When dividing 210 by 57, we get 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 2177.89473
If we take 171 away from 210, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
57 goes into 390 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 2177.894736
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
480 divided by 57 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 2177.8947368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 57 fits into 240 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 2177.89473684
Deduct 228 from 240 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 2177.89473684, with a leftover of 1.2e-08.
