We look at the division of 811087 by 80 
We want to divide 811087 by 80.

Advancing to step 1:
8 divided by 80 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 80

Going ahead to step 2:
If we divide 81 by 80, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 80 away from 81, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 80

Step 3:
The number 80 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 80

Moving on to step 4:
If we divide 110 by 80, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 80 from 110 leaves us with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 80

Going ahead to step 5:
308 divided by 80 is 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 1013.0
If we subtract 240 from 308, we get 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 80

Step 6:
The number 80 fits into 687 8 times, leaving a remainder of 47.
The next digit of our result is 8. 
Result so far: 10138.0
If we subtract 640 from 687, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
If we divide 470 by 80, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 10138.5
Subtract 400 from 470 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
80 goes into 700 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 10138.58
Subtract 640 from 700 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10138.587
Deduct 560 from 600 and we're left 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.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10138.5875
Subtract 400 from 400 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.

Moving on to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10138.5875
Subtract 0 from 0 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.

On to step 12:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10138.5875
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.

In conclusion, the division gives 10138.5875 with a balance of 0.0.
