991278 divided by 18 
We want to divide 991278 by 18.

Advancing to step 1:
The number 18 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 18

Advancing to step 2:
18 goes into 99 5 times with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 90 from 99, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 18

Going ahead to step 3:
18 can be fit into 91 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 1 after subtracting 90 from 91.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 18

Moving on to step 4:
When dividing 12 by 18, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 550.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 18

Going ahead to step 5:
If we divide 127 by 18, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 5507.0
The remainder is 1 after subtracting 126 from 127.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 18

Step 6:
If we divide 18 by 18, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 55071.0
Deduct 18 from 18 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 7:
When dividing 0 by 18, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 55071.0
If we take 0 away from 0, we end up 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 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 55071.0
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 55071.0 with a balance of 0.0.
