Let's divide 144326 by 15
Let's see how many times 15 fits into 144326.

On to step 1:
15 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 15

Advancing to step 2:
The number 15 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in 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 / 15

Moving on to step 3:
If we divide 144 by 15, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 9 after subtracting 135 from 144.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 15

Going ahead to step 4:
The number 15 fits into 93 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 90 from 93, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 15

Going ahead to step 5:
15 goes into 32 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 962.0
If we take 30 away from 32, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 15

Moving on to step 6:
If we divide 26 by 15, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 9621.0
If we subtract 15 from 26, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 9621.7
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 9621.73
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 9621.733
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 9621.733 with a remainder of 0.0005.
