We're dividing 81276512 by 80 
We're looking to find how many times 80 goes into 81276512.

Step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 80

On to step 2:
If we divide 81 by 80, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 80 from 81 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 80

On to step 3:
When dividing 12 by 80, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 80

Going ahead to step 4:
When dividing 127 by 80, we get 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 80 from 127 leaves us with 47.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 80

On to step 5:
If we divide 476 by 80, we get 5 and a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 1015.0
Deduct 400 from 476 and we're left with 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 80

Moving on to step 6:
If we divide 765 by 80, we get 9 and a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 10159.0
Deduct 720 from 765 and we're left with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 80

Advancing to step 7:
When dividing 451 by 80, we get 5 with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 101595.0
Subtract 400 from 451 to get 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 80

Moving on to step 8:
When dividing 512 by 80, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1015956.0
Subtracting 480 from 512 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
If we divide 320 by 80, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1015956.4
If we take 320 away from 320, 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.

Let's proceed to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1015956.4
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.

Moving on to step 11:
80 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: 1015956.4
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.

Our division results in 1015956.4 with a remaining 0.0.
