We look at the division of 725391 by 57 
We want to divide 725391 by 57.

Let's proceed to step 1:
57 goes into 7 0 times 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.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 57

Step 2:
The number 57 fits into 72 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 57 from 72 and we're left with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 57

Going ahead to step 3:
57 can be fit into 155 2 times, resulting in a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 41 after subtracting 114 from 155.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 57

On to step 4:
57 goes into 413 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtracting 399 from 413 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 57

Advancing to step 5:
The number 57 fits into 149 2 times, leaving a remainder of 35.
The next digit of our result is 2. 
Result so far: 1272.0
Deduct 114 from 149 and we're left with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 57

Let's proceed to step 6:
When dividing 351 by 57, we get 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 12726.0
Subtract 342 from 351 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 57, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 12726.1
Subtract 57 from 90 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
330 divided by 57 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 12726.15
Deduct 285 from 330 and we're left with 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 9:
When dividing 450 by 57, we get 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 12726.157
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.

On to step 10:
If we divide 510 by 57, we get 8 and a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 12726.1578
Subtracting 456 from 510 leaves us 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.

On to step 11:
57 goes into 540 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 12726.15789
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 12:
57 goes into 270 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 12726.157894
If we take 228 away from 270, we end up 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.

Moving on to step 13:
57 goes into 420 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 12726.1578947
Deduct 399 from 420 and we're left 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 14:
The number 57 fits into 210 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 12726.15789473
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.

The final outcome is 12726.15789473, with a leftover of 3.9e-08.
