983509 divided by 18 
Our goal is to divide 983509 by 18.

Advancing to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 18

Step 2:
The number 18 fits into 98 5 times, leaving a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 90 away from 98, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 18

On to step 3:
18 can be fit into 83 4 times, resulting in a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Deduct 72 from 83 and we're left with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 18

Advancing to step 4:
If we divide 115 by 18, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 546.0
If we subtract 108 from 115, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 18

On to step 5:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 5463.0
Subtracting 54 from 70 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 18

Going ahead to step 6:
18 goes into 169 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 54639.0
The remainder is 7 after subtracting 162 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
18 can be fit into 70 3 times, resulting in a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 54639.3
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 54639.38
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 54639.388
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 54639.388 with a remainder of 0.0016.
