Let's divide 72150 by 99
We're looking to find how many times 99 goes into 72150.

Going ahead to step 1:
99 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 99

Step 2:
99 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 99

Advancing to step 3:
99 goes into 721 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 693 from 721 leaves us with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 99

Advancing to step 4:
285 divided by 99 is 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 198 from 285 to get 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 99

Going ahead to step 5:
99 can be fit into 870 8 times, resulting in a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 728.0
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 6:
99 goes into 780 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 728.7
Subtract 693 from 780 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 7:
870 divided by 99 is 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 728.78
Subtract 792 from 870 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 8:
780 divided by 99 is 7 with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 728.787
Deduct 693 from 780 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
If we divide 870 by 99, we get 8 and a remainder of 78.
The next digit of our result is 8. 
Result so far: 728.7878
Deduct 792 from 870 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
99 goes into 780 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 728.78787
Subtracting 693 from 780 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
When dividing 870 by 99, we get 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 728.787878
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
If we divide 780 by 99, we get 7 and a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 728.7878787
Deduct 693 from 780 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
99 can be fit into 870 8 times, resulting in a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 728.78787878
Subtract 792 from 870 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 728.78787878 and a remainder of 7.8e-08.
