510939 divided by 18 
We want to divide 510939 by 18.

On to step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 18

Step 2:
When dividing 51 by 18, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 15 after subtracting 36 from 51.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 18

Going ahead to step 3:
150 divided by 18 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 28.0
If we take 144 away from 150, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 18

On to step 4:
The number 18 fits into 69 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
Subtracting 54 from 69 leaves us with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 18

On to step 5:
18 can be fit into 153 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2838.0
Subtracting 144 from 153 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 18

Moving on to step 6:
18 can be fit into 99 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 28385.0
Subtracting 90 from 99 leaves us with 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:
90 divided by 18 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28385.5
Deduct 90 from 90 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.

Advancing to step 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28385.5
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:
18 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28385.5
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.

In conclusion, the division gives 28385.5 with a balance of 0.0.
