We divide 486297 by 18
We're looking to find how many times 18 goes into 486297.

Step 1:
4 divided by 18 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 18

Step 2:
18 can be fit into 48 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 36 from 48, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Let's proceed to step 3:
126 divided by 18 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 126 from 126, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 18

Going ahead to step 4:
2 divided by 18 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 270.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 18

Let's proceed to step 5:
18 goes into 29 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 2701.0
Subtracting 18 from 29 leaves us with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 18

Advancing to step 6:
When dividing 117 by 18, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 27016.0
If we take 108 away from 117, we end up 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:
18 goes into 90 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 27016.5
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.

Let's proceed to step 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27016.5
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:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 27016.5
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.

Our division results in 27016.5 with a remaining 0.0.
