Let's divide 144339 by 18
Let's see how many times 18 fits into 144339.

Step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 18

Advancing to step 2:
If we divide 14 by 18, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 18

Step 3:
144 divided by 18 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 0 after subtracting 144 from 144.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 18

On to step 4:
The number 18 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 18

Advancing to step 5:
The number 18 fits into 33 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 801.0
If we subtract 18 from 33, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 18

Let's proceed to step 6:
18 can be fit into 159 8 times, resulting in a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 8018.0
If we subtract 144 from 159, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 18, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8018.8
The remainder is 6 after subtracting 144 from 150.
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 8:
18 goes into 60 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 8018.83
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
18 goes into 60 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 8018.833
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 8018.833 with a balance of 0.0006.
