Let's divide 399093 by 18
Let's see how many times 18 fits into 399093.

Moving on to step 1:
3 divided by 18 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 18

Advancing to step 2:
39 divided by 18 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 3 after subtracting 36 from 39.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 18

Step 3:
18 goes into 39 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 36 from 39, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 18

On to step 4:
18 can be fit into 30 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
If we subtract 18 from 30, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 18

Step 5:
If we divide 129 by 18, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2217.0
If we take 126 away from 129, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

On to step 6:
When dividing 33 by 18, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 22171.0
Subtract 18 from 33 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.

Let's proceed to step 7:
150 divided by 18 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 22171.8
If we subtract 144 from 150, we get 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 8:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 22171.83
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 22171.833
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 22171.833 with a remaining 0.0006.
