We look at the division of 812781 by 80 
We want to figure out the number of times 812781 can be divided by 80.

Moving on to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 80

Step 2:
When dividing 81 by 80, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 80 from 81.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 80

On to step 3:
If we divide 12 by 80, we get 0 and a remainder of 12.
Write down 0 as next digit of the 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:
127 divided by 80 is 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtract 80 from 127 to get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 80

Let's proceed to step 5:
478 divided by 80 is 5 with a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 1015.0
Deduct 400 from 478 and we're left with 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 80

Moving on to step 6:
When dividing 781 by 80, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 10159.0
If we take 720 away from 781, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
80 goes into 610 7 times with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 10159.7
Subtracting 560 from 610 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 10159.76
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 10159.762
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10159.7625
If we take 400 away from 400, 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.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10159.7625
Deduct 0 from 0 and we're left 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 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10159.7625
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.

Our division results in 10159.7625 with a remaining 0.0.
