We're dividing 728663 by 15 
Our goal is to divide 728663 by 15.

Advancing to step 1:
7 divided by 15 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 15

On to step 2:
If we divide 72 by 15, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 60 from 72 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 15

Advancing to step 3:
128 divided by 15 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 120 away from 128, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 15

Going ahead to step 4:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 485.0
Subtract 75 from 86 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 15

Step 5:
116 divided by 15 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 4857.0
Subtracting 105 from 116 leaves us with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 15

Advancing to step 6:
If we divide 113 by 15, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 48577.0
If we subtract 105 from 113, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
15 goes into 80 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 48577.5
The remainder is 5 after subtracting 75 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 48577.53
If we subtract 45 from 50, we get 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 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 48577.533
If we subtract 45 from 50, we get 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 outcome is 48577.533, with a leftover of 0.0005.
