We divide 491727 by 18
We're looking to find how many times 18 goes into 491727.

Step 1:
18 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 18

Let's proceed to step 2:
The number 18 fits into 49 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 36 from 49 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 18

On to step 3:
The number 18 fits into 131 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 5 after subtracting 126 from 131.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 18

Step 4:
When dividing 57 by 18, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 273.0
Deduct 54 from 57 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 18

Advancing to step 5:
When dividing 32 by 18, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2731.0
Deduct 18 from 32 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 18

On to step 6:
18 can be fit into 147 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 27318.0
Deduct 144 from 147 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 18, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 27318.1
Subtract 18 from 30 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 27318.16
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 27318.166
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 27318.166, with a leftover of 0.0012.
