We look at the division of 993381 by 18 
Let's see how many times 18 fits into 993381.

Going ahead to step 1:
9 divided by 18 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 18

On to step 2:
If we divide 99 by 18, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 90 away from 99, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 18

On to step 3:
18 goes into 93 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 90 away from 93, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 18

Advancing to step 4:
When dividing 33 by 18, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
Subtracting 18 from 33 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 18

Going ahead to step 5:
18 can be fit into 158 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 5518.0
Subtract 144 from 158 to get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 18

Let's proceed to step 6:
The number 18 fits into 141 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 55187.0
Subtract 126 from 141 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 55187.8
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
18 can be fit into 60 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 55187.83
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 55187.833
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 55187.833 with a remainder of 0.0006.
