Let's divide 393480 by 18
We want to figure out the number of times 393480 can be divided by 18.

Moving on to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 18

On to step 2:
18 can be fit into 39 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 18

Advancing to step 3:
18 can be fit into 33 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 18 from 33, we get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 18

On to step 4:
18 goes into 154 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Subtracting 144 from 154 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 18

Going ahead to step 5:
108 divided by 18 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2186.0
If we subtract 108 from 108, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 18

On to step 6:
If we divide 0 by 18, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21860.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 21860.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21860.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 21860.0 with a balance of 0.0.
