Let's divide 449870 by 18
Our goal is to divide 449870 by 18.

Advancing to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 18

Step 2:
18 can be fit into 44 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 36 from 44 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

Step 3:
18 goes into 89 4 times with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 72 from 89 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 18

Advancing to step 4:
When dividing 178 by 18, we get 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 249.0
The remainder is 16 after subtracting 162 from 178.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 18

Let's proceed to step 5:
18 goes into 167 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 2499.0
Deduct 162 from 167 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 18

On to step 6:
When dividing 50 by 18, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 24992.0
Subtracting 36 from 50 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 18 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 24992.7
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 24992.77
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 24992.77, with a leftover of 0.014.
