We look at the division of 491650 by 18 
We're looking to find how many times 18 goes into 491650.

Moving on to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 18

Let's proceed to step 2:
When dividing 49 by 18, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 36 from 49 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 18

Going ahead to step 3:
18 goes into 131 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 126 from 131 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 18

Let's proceed to step 4:
18 goes into 56 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 273.0
Subtract 54 from 56 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 18

Going ahead to step 5:
25 divided by 18 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 2731.0
If we take 18 away from 25, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 18

On to step 6:
18 goes into 70 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 27313.0
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 27313.8
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 27313.88
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 27313.88, with a leftover of 0.016.
