We look at the division of 429723 by 15 
Our goal is to divide 429723 by 15.

Step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 15

Advancing to step 2:
If we divide 42 by 15, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 30 from 42 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 15

Moving on to step 3:
When dividing 129 by 15, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 9 after subtracting 120 from 129.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

On to step 4:
97 divided by 15 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 286.0
Subtract 90 from 97 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

On to step 5:
If we divide 72 by 15, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 2864.0
Subtract 60 from 72 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 15

Moving on to step 6:
123 divided by 15 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 28648.0
Subtracting 120 from 123 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
15 can be fit into 30 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 28648.2
Subtracting 30 from 30 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.

Advancing to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28648.2
If we take 0 away from 0, we end up 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 9:
15 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: 28648.2
If we take 0 away from 0, we end up 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.

Our division results in 28648.2 with a remaining 0.0.
