91817 ÷ 9 
We want to divide 91817 by 9.

On to step 1:
If we divide 9 by 9, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 9

Advancing to step 2:
1 divided by 9 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

On to step 3:
When dividing 18 by 9, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 18 from 18, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 9

Going ahead to step 4:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 9

Going ahead to step 5:
9 goes into 17 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10201.0
Subtracting 9 from 17 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 6:
If we divide 80 by 9, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 10201.8
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
If we divide 80 by 9, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10201.88
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 10201.88 with a remaining 0.008.
