We're dividing 123317 by 18 
We want to divide 123317 by 18.

Step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 18

On to step 2:
18 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

Moving on to step 3:
If we divide 123 by 18, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 108 from 123 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 18

Going ahead to step 4:
153 divided by 18 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 68.0
The remainder is 9 after subtracting 144 from 153.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 18

Advancing to step 5:
91 divided by 18 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 685.0
If we subtract 90 from 91, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 18

Going ahead to step 6:
18 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 6850.0
If we subtract 0 from 17, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 18, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 6850.9
Subtracting 162 from 170 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 8:
When dividing 80 by 18, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 6850.94
If we take 72 away from 80, we end up 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 9:
When dividing 80 by 18, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 6850.944
If we take 72 away from 80, we end up 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.

The quotient of the division is 6850.944, and the remainder is 0.0008.
