Let's divide 991976 by 18
We're looking to find how many times 18 goes into 991976.

Let's proceed to step 1:
If we divide 9 by 18, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 18

Moving on to step 2:
18 goes into 99 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 90 from 99, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 18

Moving on to step 3:
91 divided by 18 is 5 with 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.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 18

Step 4:
When dividing 19 by 18, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
The remainder is 1 after subtracting 18 from 19.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 18

On to step 5:
If we divide 17 by 18, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 5510.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 18

Moving on to step 6:
The number 18 fits into 176 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 55109.0
If we subtract 162 from 176, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 55109.7
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 55109.77
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 55109.77 and a remainder of 0.014.
