Let's divide 45120 by 57
We want to figure out the number of times 45120 can be divided by 57.

Moving on to step 1:
57 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 57

Step 2:
The number 57 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 57

Advancing to step 3:
451 divided by 57 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 399 from 451 leaves us with 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 57

On to step 4:
57 can be fit into 522 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
The remainder is 9 after subtracting 513 from 522.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 57

Advancing to step 5:
If we divide 90 by 57, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 791.0
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.

Advancing to step 6:
If we divide 330 by 57, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 791.5
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
57 goes into 450 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 791.57
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.

Advancing to step 8:
57 goes into 510 8 times with a remainder of 54.
The next digit of our result is 8. 
Result so far: 791.578
If we take 456 away from 510, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
57 goes into 540 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 791.5789
Subtracting 513 from 540 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
270 divided by 57 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 791.57894
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.

Going ahead to step 11:
When dividing 420 by 57, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 791.578947
If we take 399 away from 420, we end up 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 12:
When dividing 210 by 57, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 791.5789473
Deduct 171 from 210 and we're left 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 13:
The number 57 fits into 390 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 791.57894736
Deduct 342 from 390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 791.57894736 and a remainder of 4.8e-08.
