855998 divided by 80 
We want to divide 855998 by 80.

Going ahead to step 1:
8 divided by 80 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 80

Step 2:
85 divided by 80 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 80 from 85.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 80

Going ahead to step 3:
80 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 55, we end up with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 80

On to step 4:
80 goes into 559 6 times with a remainder of 79.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we take 480 away from 559, we end up with 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 80

Moving on to step 5:
80 goes into 799 9 times with a remainder of 79.
The next digit of our result is 9. 
Result so far: 1069.0
Deduct 720 from 799 and we're left with 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 80

Moving on to step 6:
80 can be fit into 798 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 10699.0
Deduct 720 from 798 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
780 divided by 80 is 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 10699.9
Subtract 720 from 780 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.

On to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 10699.97
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10699.975
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.

On to step 10:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10699.975
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.

Step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10699.975
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 10699.975 with a balance of 0.0.
