We look at the division of 723429 by 57 
We want to divide 723429 by 57.

Advancing to step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 57

Going ahead to step 2:
72 divided by 57 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 72, we get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 57

Let's proceed to step 3:
If we divide 153 by 57, we get 2 and a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 114 away from 153, we end up with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 57

Moving on to step 4:
57 can be fit into 394 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we subtract 342 from 394, we get 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 57

On to step 5:
If we divide 522 by 57, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 1269.0
Deduct 513 from 522 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 57

Advancing to step 6:
The number 57 fits into 99 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 12691.0
Subtract 57 from 99 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
57 goes into 420 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 12691.7
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.

Step 8:
57 goes into 210 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 12691.73
Subtracting 171 from 210 leaves us 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 9:
390 divided by 57 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 12691.736
The remainder is 48 after subtracting 342 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 57 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 12691.7368
The remainder is 24 after subtracting 456 from 480.
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 11:
When dividing 240 by 57, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 12691.73684
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
57 goes into 120 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 12691.736842
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
57 goes into 60 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 12691.7368421
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
If we divide 30 by 57, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 12691.7368421
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 12691.7368421, and the remainder is 3e-08.
