We're dividing 81512 by 8 
We're looking to find how many times 8 goes into 81512.

Let's proceed to step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 8

Step 2:
8 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 8

Step 3:
The number 8 fits into 15 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtracting 8 from 15 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 8

Going ahead to step 4:
The number 8 fits into 71 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
Subtracting 64 from 71 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 8

On to step 5:
72 divided by 8 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 10189.0
Subtract 72 from 72 to 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.

Going ahead to step 6:
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: 10189.0
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.

Advancing to step 7:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10189.0
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.

Our division results in 10189.0 with a remaining 0.0.
