991885 ÷ 18 
We're looking to find how many times 18 goes into 991885.

Step 1:
18 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 18

On to step 2:
The number 18 fits into 99 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 90 from 99 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 18

Going ahead to step 3:
If we divide 91 by 18, we get 5 and 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.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 18

Moving on to step 4:
When dividing 18 by 18, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 551.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 18

Advancing to step 5:
If we divide 8 by 18, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 5510.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 18

Step 6:
18 can be fit into 85 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 55104.0
The remainder is 13 after subtracting 72 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
18 can be fit into 130 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 55104.7
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 18, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 55104.72
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
18 goes into 40 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 55104.722
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 55104.722 with a balance of 0.0004.
