We're dividing 99612336 by 8 
We want to figure out the number of times 99612336 can be divided by 8.

Step 1:
The number 8 fits into 9 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 8 from 9 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 8

Advancing to step 2:
The number 8 fits into 19 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 16 from 19 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 8

Step 3:
36 divided by 8 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtracting 32 from 36 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 8

Let's proceed to step 4:
41 divided by 8 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1245.0
If we take 40 away from 41, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 8

Going ahead to step 5:
If we divide 12 by 8, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 12451.0
Subtract 8 from 12 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

Going ahead to step 6:
43 divided by 8 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 124515.0
Deduct 40 from 43 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 8

Going ahead to step 7:
33 divided by 8 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 1245154.0
Subtracting 32 from 33 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 8

On to step 8:
The number 8 fits into 16 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12451542.0
If we take 16 away from 16, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12451542.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12451542.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 12451542.0 with a remainder of 0.0.
