448386 ÷ 18 
We want to figure out the number of times 448386 can be divided by 18.

Moving on to step 1:
18 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 18

On to step 2:
18 can be fit into 44 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 36 away from 44, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 18

Let's proceed to step 3:
If we divide 88 by 18, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 72 from 88, we get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 18

Let's proceed to step 4:
18 can be fit into 163 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 249.0
Subtract 162 from 163 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 18

Let's proceed to step 5:
18 divided by 18 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 2491.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 18

Advancing to step 6:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 24910.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 24910.3
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
18 can be fit into 60 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 24910.33
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 24910.33 and a remainder of 0.006.
