We're dividing 990984 by 18 
Our goal is to divide 990984 by 18.

Moving on to step 1:
If we divide 9 by 18, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 18

Moving on to step 2:
If we divide 99 by 18, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 90 away from 99, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 18

Moving on to step 3:
When dividing 90 by 18, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 90 from 90 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 18

On to step 4:
When dividing 9 by 18, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 550.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 18

Going ahead to step 5:
98 divided by 18 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5505.0
Subtract 90 from 98 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 18

Moving on to step 6:
84 divided by 18 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 55054.0
If we subtract 72 from 84, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 55054.6
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 55054.66
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 55054.66, and the remainder is 0.012.
