We look at the division of 120308 by 8 
We're looking to find how many times 8 goes into 120308.

Step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Let's proceed to step 2:
When dividing 12 by 8, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 8 from 12, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 8

Moving on to step 3:
When dividing 40 by 8, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 40 from 40 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 8

Advancing to step 4:
If we divide 3 by 8, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 150.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 8

Advancing to step 5:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 1503.0
If we take 24 away from 30, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 8

Going ahead to step 6:
8 can be fit into 68 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 15038.0
Subtract 64 from 68 to 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.

Step 7:
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: 15038.5
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.

Step 8:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15038.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15038.5
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.

The final result is 15038.5 with a remainder of 0.0.
