We divide 811768 by 80
We want to figure out the number of times 811768 can be divided by 80.

On to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 80

On to step 2:
81 divided by 80 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 80 from 81.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 80

On to step 3:
If we divide 11 by 80, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 11 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 80

Going ahead to step 4:
80 goes into 117 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 80 from 117 to get 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 80

Advancing to step 5:
80 goes into 376 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 1014.0
If we take 320 away from 376, we end up with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 80

Going ahead to step 6:
If we divide 568 by 80, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 10147.0
Subtract 560 from 568 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
80 can be fit into 80 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 10147.1
Deduct 80 from 80 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.

On to step 8:
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: 10147.1
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.

Let's proceed to step 9:
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: 10147.1
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.

The final result is 10147.1 with a remainder of 0.0.
