255393 divided by 18 
We want to figure out the number of times 255393 can be divided by 18.

Moving on to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 18

Going ahead to step 2:
When dividing 25 by 18, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 25, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 18

Advancing to step 3:
If we divide 75 by 18, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 72 from 75 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 18

Let's proceed to step 4:
The number 18 fits into 33 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
If we take 18 away from 33, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 18

On to step 5:
When dividing 159 by 18, we get 8 with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 1418.0
Deduct 144 from 159 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 18

Step 6:
When dividing 153 by 18, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 14188.0
Subtract 144 from 153 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 14188.5
Subtracting 90 from 90 leaves us 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.

Moving on to step 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14188.5
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.

Let's proceed to step 9:
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: 14188.5
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.

The final outcome is 14188.5, with a leftover of 0.0.
