We look at the division of 79978181 by 792 
We want to figure out the number of times 79978181 can be divided by 792.

On to step 1:
When dividing 7 by 792, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 792

Going ahead to step 2:
792 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 792

Advancing to step 3:
799 divided by 792 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 792 from 799 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 792

On to step 4:
When dividing 77 by 792, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 792

Advancing to step 5:
792 goes into 778 0 times with a remainder of 778.
The next digit of our result is 0. 
Result so far: 100.0
If we subtract 0 from 778, we get 778.
Append the next digit (1) from the dividend to 778 and continue with: 7781 / 792

Let's proceed to step 6:
If we divide 7781 by 792, we get 9 and a remainder of 653.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
Deduct 7128 from 7781 and we're left with 653.
Bring next digit (8) of the dividend behind the 653 and repeat the process: 6538 / 792

Step 7:
792 can be fit into 6538 8 times, resulting in a remainder of 202.
Record the quotient 8 as the next digit in the result. 
Result so far: 10098.0
Subtract 6336 from 6538 to get 202.
Take the next digit (1) from the dividend and append it to 202, then repeat: 2021 / 792

On to step 8:
792 goes into 2021 2 times with a remainder of 437.
Record the quotient 2 as the next digit in the result. 
Result so far: 100982.0
If we subtract 1584 from 2021, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 9:
792 can be fit into 4370 5 times, resulting in a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 100982.5
If we take 3960 away from 4370, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
4100 divided by 792 is 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 100982.55
If we subtract 3960 from 4100, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 100982.55 with a remaining 0.14.
