728542 ÷ 15 
We want to figure out the number of times 728542 can be divided by 15.

Advancing to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
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

On to step 2:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 60 from 72, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 15

Moving on to step 3:
15 goes into 128 8 times 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.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 15

Moving on to step 4:
If we divide 85 by 15, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 485.0
The remainder is 10 after subtracting 75 from 85.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 15

Moving on to step 5:
104 divided by 15 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 4856.0
If we take 90 away from 104, we end up with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 15

On to step 6:
If we divide 142 by 15, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 48569.0
Deduct 135 from 142 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
15 can be fit into 70 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 48569.4
Subtract 60 from 70 to 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.

Step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 48569.46
Subtracting 90 from 100 leaves us 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 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 48569.466
If we subtract 90 from 100, 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.

Our division results in 48569.466 with a remaining 0.001.
