Let's divide 991016 by 18
We're looking to find how many times 18 goes into 991016.

On to step 1:
The number 18 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 18

On to step 2:
The number 18 fits into 99 5 times, leaving a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 90 from 99 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 18

Let's proceed to step 3:
The number 18 fits into 91 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 90 from 91 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 18

Let's proceed to step 4:
18 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 550.0
If we take 0 away from 10, we end up with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 18

Step 5:
When dividing 101 by 18, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5505.0
Subtracting 90 from 101 leaves us with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 18

Let's proceed to step 6:
The number 18 fits into 116 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 55056.0
Subtracting 108 from 116 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 7:
80 divided by 18 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 55056.4
Subtract 72 from 80 to get 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 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 55056.44
Subtract 72 from 80 to get 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 final outcome is 55056.44, with a leftover of 0.008.
