449688 divided by 18 
We're looking to find how many times 18 goes into 449688.

On to step 1:
4 divided by 18 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 18

On to step 2:
44 divided by 18 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 36 away from 44, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

Step 3:
When dividing 89 by 18, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 72 from 89 and we're left with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 18

Advancing to step 4:
176 divided by 18 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 249.0
Subtract 162 from 176 to get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 18

Going ahead to step 5:
If we divide 148 by 18, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2498.0
Subtract 144 from 148 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 18

Going ahead to step 6:
The number 18 fits into 48 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 24982.0
Deduct 36 from 48 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.

On to step 7:
120 divided by 18 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 24982.6
Subtracting 108 from 120 leaves us 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.

Let's proceed to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 24982.66
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 result is 24982.66 with a remainder of 0.012.
