We look at the division of 79793982 by 972 
We want to divide 79793982 by 972.

Step 1:
When dividing 7 by 972, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 972

On to step 2:
79 divided by 972 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 972

Going ahead to step 3:
When dividing 797 by 972, we get 0 with a remainder of 797.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 797 to get 797.
Fetch the next digit (9) from the dividend, attach it to 797 and continue: 7979 / 972

Going ahead to step 4:
When dividing 7979 by 972, we get 8 with a remainder of 203.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7776 from 7979 to get 203.
Grab the next digit (3) from the dividend, add it to 203, then carry on: 2033 / 972

Going ahead to step 5:
2033 divided by 972 is 2 with a remainder of 89.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 1944 from 2033 and we're left with 89.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 972

Let's proceed to step 6:
If we divide 899 by 972, we get 0 and a remainder of 899.
Use 0 as the next digit of our solution. 
Result so far: 820.0
If we take 0 away from 899, we end up with 899.
Include the next digit (8) from the dividend after 899, then repeat: 8998 / 972

Going ahead to step 7:
8998 divided by 972 is 9 with a remainder of 250.
Put 9 as the next digit of the answer. 
Result so far: 8209.0
Subtracting 8748 from 8998 leaves us with 250.
Bring next digit (2) of the dividend behind the 250 and repeat the process: 2502 / 972

Going ahead to step 8:
972 goes into 2502 2 times with a remainder of 558.
The next digit of our result is 2. 
Result so far: 82092.0
If we subtract 1944 from 2502, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 9:
972 can be fit into 5580 5 times, resulting in a remainder of 720.
Write down 5 as next digit of the result. 
Result so far: 82092.5
If we take 4860 away from 5580, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 10:
If we divide 7200 by 972, we get 7 and a remainder of 396.
Put 7 as the next digit of the answer. 
Result so far: 82092.57
The remainder is 396 after subtracting 6804 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 11:
When dividing 3960 by 972, we get 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 82092.574
If we subtract 3888 from 3960, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
If we divide 720 by 972, we get 0 and a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 82092.574
If we take 0 away from 720, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 13:
When dividing 7200 by 972, we get 7 with a remainder of 396.
Use 7 as the next digit of our solution. 
Result so far: 82092.57407
If we subtract 6804 from 7200, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 14:
972 goes into 3960 4 times with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 82092.574074
If we take 3888 away from 3960, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
972 goes into 720 0 times with a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 82092.574074
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 16:
When dividing 7200 by 972, we get 7 with a remainder of 396.
The next digit of our result is 7. 
Result so far: 82092.57407407
If we take 6804 away from 7200, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The quotient of the division is 82092.57407407, and the remainder is 3.96e-07.
