We look at the division of 120812 by 8 
Let's see how many times 8 fits into 120812.

Let's proceed to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 8

Let's proceed to step 2:
If we divide 12 by 8, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 8 away from 12, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 8

On to step 3:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 40 from 40 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 8

Going ahead to step 4:
8 goes into 8 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 151.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 8

Step 5:
8 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 1510.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 8

On to step 6:
8 goes into 12 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 15101.0
If we subtract 8 from 12, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 8, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15101.5
If we subtract 40 from 40, 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.

Moving on to step 8:
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: 15101.5
If we take 0 away from 0, 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.

Step 9:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15101.5
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.

Our division results in 15101.5 with a remaining 0.0.
