15495356 divided by 728 
We're looking to find how many times 728 goes into 15495356.

On to step 1:
If we divide 1 by 728, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 728

On to step 2:
728 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 728

Going ahead to step 3:
728 goes into 154 0 times with a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Grab the next digit (9) from the dividend, add it to 154, then carry on: 1549 / 728

Step 4:
728 goes into 1549 2 times with a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1456 from 1549 leaves us with 93.
Fetch the next digit (5) from the dividend, attach it to 93 and continue: 935 / 728

Let's proceed to step 5:
If we divide 935 by 728, we get 1 and a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 728 from 935 leaves us with 207.
Include the next digit (3) from the dividend after 207, then repeat: 2073 / 728

On to step 6:
728 can be fit into 2073 2 times, resulting in a remainder of 617.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
The remainder is 617 after subtracting 1456 from 2073.
Append the next digit (5) from the dividend to 617 and continue with: 6175 / 728

Advancing to step 7:
The number 728 fits into 6175 8 times, leaving a remainder of 351.
The number 8 becomes the next digit in our result. 
Result so far: 2128.0
The remainder is 351 after subtracting 5824 from 6175.
Grab the next digit (6) from the dividend, add it to 351, then carry on: 3516 / 728

On to step 8:
If we divide 3516 by 728, we get 4 and a remainder of 604.
The next digit of our result is 4. 
Result so far: 21284.0
If we take 2912 away from 3516, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 9:
6040 divided by 728 is 8 with a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 21284.8
The remainder is 216 after subtracting 5824 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
When dividing 2160 by 728, we get 2 with a remainder of 704.
The next digit of our result is 2. 
Result so far: 21284.82
If we take 1456 away from 2160, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 11:
7040 divided by 728 is 9 with a remainder of 488.
Put 9 as the next digit of the answer. 
Result so far: 21284.829
If we take 6552 away from 7040, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 12:
When dividing 4880 by 728, we get 6 with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 21284.8296
Subtracting 4368 from 4880 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 13:
728 can be fit into 5120 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 21284.82967
Deduct 5096 from 5120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
The number 728 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 21284.82967
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
728 can be fit into 2400 3 times, resulting in a remainder of 216.
Put 3 as the next digit of the answer. 
Result so far: 21284.8296703
The remainder is 216 after subtracting 2184 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 16:
The number 728 fits into 2160 2 times, leaving a remainder of 704.
The number 2 becomes the next digit in our result. 
Result so far: 21284.82967032
If we subtract 1456 from 2160, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

After the division, we end up with 21284.82967032 and a remainder of 7.04e-07.
