We divide 866996 by 80
We want to divide 866996 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 (6) from the dividend, add it to 8, then carry on: 86 / 80

Going ahead to step 2:
80 goes into 86 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 80 away from 86, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 80

Going ahead to step 3:
The number 80 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 66 to get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 80

Going ahead to step 4:
80 can be fit into 669 8 times, resulting in a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtracting 640 from 669 leaves us with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 80

Advancing to step 5:
When dividing 299 by 80, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 1083.0
Subtracting 240 from 299 leaves us with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 80

Moving on to step 6:
When dividing 596 by 80, we get 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 10837.0
Deduct 560 from 596 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
360 divided by 80 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 10837.4
Deduct 320 from 360 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.

Advancing to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10837.45
Deduct 400 from 400 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 9:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10837.45
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.

Moving on to step 10:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10837.45
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.

Our division results in 10837.45 with a remaining 0.0.
