We look at the division of 79009721 by 981 
We want to divide 79009721 by 981.

Step 1:
If we divide 7 by 981, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 981

Step 2:
981 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 981

Let's proceed to step 3:
981 can be fit into 790 0 times, resulting in a remainder of 790.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 790 and we're left with 790.
Append the next digit (0) from the dividend to 790 and continue with: 7900 / 981

Moving on to step 4:
7900 divided by 981 is 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7848 from 7900 leaves us with 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 981

Moving on to step 5:
529 divided by 981 is 0 with a remainder of 529.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 529 leaves us with 529.
Append the next digit (7) from the dividend to 529 and continue with: 5297 / 981

Moving on to step 6:
981 goes into 5297 5 times with a remainder of 392.
Put 5 as the next digit of the answer. 
Result so far: 805.0
If we subtract 4905 from 5297, we get 392.
Grab the next digit (2) from the dividend, add it to 392, then carry on: 3922 / 981

On to step 7:
If we divide 3922 by 981, we get 3 and a remainder of 979.
Record the quotient 3 as the next digit in the result. 
Result so far: 8053.0
If we take 2943 away from 3922, we end up with 979.
Grab the next digit (1) from the dividend, add it to 979, then carry on: 9791 / 981

Advancing to step 8:
981 goes into 9791 9 times with a remainder of 962.
The number 9 becomes the next digit in our result. 
Result so far: 80539.0
If we take 8829 away from 9791, we end up with 962.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9620, and continue the process.

Moving on to step 9:
9620 divided by 981 is 9 with a remainder of 791.
Record the quotient 9 as the next digit in the result. 
Result so far: 80539.9
The remainder is 791 after subtracting 8829 from 9620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

On to step 10:
7910 divided by 981 is 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 80539.98
The remainder is 62 after subtracting 7848 from 7910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
981 can be fit into 620 0 times, resulting in a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 80539.98
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 12:
6200 divided by 981 is 6 with a remainder of 314.
Put 6 as the next digit of the answer. 
Result so far: 80539.9806
If we take 5886 away from 6200, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 13:
If we divide 3140 by 981, we get 3 and a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 80539.98063
If we subtract 2943 from 3140, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 14:
When dividing 1970 by 981, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 80539.980632
Subtracting 1962 from 1970 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 15:
The number 981 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 80539.980632
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
981 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 80539.980632
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

In conclusion, the division gives 80539.980632 with a balance of 8e-07.
