We're dividing 729210 by 57 
Our goal is to divide 729210 by 57.

Step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 57

On to step 2:
The number 57 fits into 72 1 times, leaving 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.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 57

Step 3:
57 goes into 159 2 times with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 114 from 159 to get 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 57

Going ahead to step 4:
452 divided by 57 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 127.0
Deduct 399 from 452 and we're left with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 57

On to step 5:
If we divide 531 by 57, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
If we subtract 513 from 531, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 57

Moving on to step 6:
The number 57 fits into 180 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 12793.0
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 57 fits into 90 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 12793.1
If we take 57 away from 90, we end up 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.

Moving on to step 8:
When dividing 330 by 57, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 12793.15
If we take 285 away from 330, we end up 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:
450 divided by 57 is 7 with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 12793.157
The remainder is 51 after subtracting 399 from 450.
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 10:
57 can be fit into 510 8 times, resulting in a remainder of 54.
The next digit of our result is 8. 
Result so far: 12793.1578
The remainder is 54 after subtracting 456 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
The number 57 fits into 540 9 times, leaving a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 12793.15789
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 12793.157894
Deduct 228 from 270 and we're left 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.

Advancing to step 13:
57 goes into 420 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 12793.1578947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
57 goes into 210 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 12793.15789473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 12793.15789473 and a remainder of 3.9e-08.
