991579 divided by 18 
We want to divide 991579 by 18.

Moving on to step 1:
18 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 18

On to step 2:
18 goes into 99 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 9 after subtracting 90 from 99.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 18

Moving on to step 3:
18 can be fit into 91 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 1 after subtracting 90 from 91.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 18

Let's proceed to step 4:
If we divide 15 by 18, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 550.0
If we take 0 away from 15, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 18

Moving on to step 5:
18 goes into 157 8 times with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 5508.0
Deduct 144 from 157 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 18

On to step 6:
18 goes into 139 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 55087.0
If we subtract 126 from 139, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
The number 18 fits into 130 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 55087.7
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.

Let's proceed to step 8:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 55087.72
If we subtract 36 from 40, 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.

Step 9:
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: 55087.722
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 55087.722 with a balance of 0.0004.
