393013 ÷ 18 
Our goal is to divide 393013 by 18.

On to step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of 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

Step 2:
18 goes into 39 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 36 from 39 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 18

Let's proceed to step 3:
33 divided by 18 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 18 from 33 and we're left with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 18

Advancing to step 4:
150 divided by 18 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Subtracting 144 from 150 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 18

Going ahead to step 5:
18 can be fit into 61 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 2183.0
The remainder is 7 after subtracting 54 from 61.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 18

Let's proceed to step 6:
The number 18 fits into 73 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 21834.0
If we subtract 72 from 73, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 18 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21834.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 21834.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 21834.055
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 21834.055, with a leftover of 0.001.
