We look at the division of 725815 by 15 
Our goal is to divide 725815 by 15.

Advancing to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 15

Moving on to step 2:
72 divided by 15 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 72 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 15

Moving on to step 3:
15 can be fit into 125 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 120 from 125 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 15

Step 4:
15 goes into 58 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 483.0
If we take 45 away from 58, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 15

Step 5:
15 goes into 131 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 4838.0
If we subtract 120 from 131, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 15

On to step 6:
When dividing 115 by 15, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 48387.0
If we subtract 105 from 115, 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 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 48387.6
Deduct 90 from 100 and we're left 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.

Let's proceed to step 8:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 48387.66
The remainder is 10 after subtracting 90 from 100.
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 48387.66 and a remainder of 0.01.
