We're dividing 490311 by 18 
Let's see how many times 18 fits into 490311.

Going ahead to step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 18

Moving on to step 2:
If we divide 49 by 18, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 13 after subtracting 36 from 49.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 18

Step 3:
18 can be fit into 130 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 4 after subtracting 126 from 130.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 18

Advancing to step 4:
43 divided by 18 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 272.0
If we take 36 away from 43, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Let's proceed to step 5:
18 goes into 71 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 2723.0
Deduct 54 from 71 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 18

Advancing to step 6:
When dividing 171 by 18, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 27239.0
The remainder is 9 after subtracting 162 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving 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: 27239.5
Subtract 90 from 90 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.

Going ahead to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27239.5
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.

Going ahead to step 9:
When dividing 0 by 18, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27239.5
Subtracting 0 from 0 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.

The final outcome is 27239.5, with a leftover of 0.0.
