We look at the division of 72108 by 99 
Our goal is to divide 72108 by 99.

On to step 1:
If we divide 7 by 99, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in 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 / 99

Step 2:
99 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 99

Going ahead to step 3:
When dividing 721 by 99, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 693 from 721 leaves us with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 99

Going ahead to step 4:
280 divided by 99 is 2 with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 82 after subtracting 198 from 280.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 99

Let's proceed to step 5:
99 goes into 828 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 728.0
Subtracting 792 from 828 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 6:
360 divided by 99 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 728.3
Deduct 297 from 360 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
If we divide 630 by 99, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 728.36
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
99 goes into 360 3 times with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 728.363
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
99 goes into 630 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 728.3636
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
360 divided by 99 is 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 728.36363
The remainder is 63 after subtracting 297 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 728.363636
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
99 can be fit into 360 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 728.3636363
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 13:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 728.36363636
If we subtract 594 from 630, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 728.36363636 and a remainder of 3.6e-08.
