We look at the division of 509301 by 18 
We want to divide 509301 by 18.

Moving on to step 1:
If we divide 5 by 18, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 18

Advancing to step 2:
If we divide 50 by 18, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 36 from 50 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 18

Let's proceed to step 3:
149 divided by 18 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 5 after subtracting 144 from 149.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 18

Let's proceed to step 4:
If we divide 53 by 18, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
If we subtract 36 from 53, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 18

Step 5:
When dividing 170 by 18, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 2829.0
The remainder is 8 after subtracting 162 from 170.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 18

Let's proceed to step 6:
18 goes into 81 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 28294.0
The remainder is 9 after subtracting 72 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
18 can be fit into 90 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 28294.5
If we subtract 90 from 90, we 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 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28294.5
If we subtract 0 from 0, we 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.

Step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 28294.5
If we subtract 0 from 0, we 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.

The final outcome is 28294.5, with a leftover of 0.0.
