Let's divide 438507 by 18
We want to divide 438507 by 18.

Let's proceed to step 1:
18 can be fit into 4 0 times, resulting in 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.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 18

Let's proceed to step 2:
43 divided by 18 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 7 after subtracting 36 from 43.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 18

On to step 3:
18 goes into 78 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 72 from 78, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 18

Advancing to step 4:
When dividing 65 by 18, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 243.0
Subtract 54 from 65 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 18

On to step 5:
18 goes into 110 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2436.0
If we take 108 away from 110, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 18

Moving on to step 6:
18 goes into 27 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 24361.0
Subtracting 18 from 27 leaves us 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.

On 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: 24361.5
The remainder is 0 after subtracting 90 from 90.
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:
18 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24361.5
Subtract 0 from 0 to get 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 9:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24361.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 24361.5 and a remainder of 0.0.
