We look at the division of 142449 by 15 
Let's see how many times 15 fits into 142449.

Advancing to step 1:
1 divided by 15 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 15

Let's proceed to step 2:
The number 15 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 15

Moving on to step 3:
If we divide 142 by 15, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 135 from 142 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 15

Let's proceed to step 4:
15 goes into 74 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we take 60 away from 74, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 15

On to step 5:
If we divide 144 by 15, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 949.0
The remainder is 9 after subtracting 135 from 144.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 15

Step 6:
15 can be fit into 99 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 9496.0
The remainder is 9 after subtracting 90 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 15, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 9496.6
Subtracting 90 from 90 leaves us with 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 8:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9496.6
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:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9496.6
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.

After the division, we end up with 9496.6 and a remainder of 0.0.
