Let's divide 439948 by 18
We want to divide 439948 by 18.

Going ahead to step 1:
18 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 18

On to step 2:
43 divided by 18 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 36 from 43, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 18

Step 3:
18 can be fit into 79 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 72 from 79, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 18

Step 4:
If we divide 79 by 18, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 244.0
Subtract 72 from 79 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 18

Step 5:
18 can be fit into 74 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 2444.0
Deduct 72 from 74 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 18

Going ahead to step 6:
The number 18 fits into 28 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 24441.0
Subtracting 18 from 28 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 24441.5
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 24441.55
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 24441.55 and a remainder of 0.01.
