We're dividing 15687776 by 728 
We're looking to find how many times 728 goes into 15687776.

Step 1:
When dividing 1 by 728, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 728

Moving on to step 2:
728 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 728

Advancing to step 3:
The number 728 fits into 156 0 times, leaving a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Grab the next digit (8) from the dividend, add it to 156, then carry on: 1568 / 728

Step 4:
728 can be fit into 1568 2 times, resulting in a remainder of 112.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 112 after subtracting 1456 from 1568.
Bring next digit (7) of the dividend behind the 112 and repeat the process: 1127 / 728

On to step 5:
1127 divided by 728 is 1 with a remainder of 399.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 728 from 1127, we get 399.
Fetch the next digit (7) from the dividend, attach it to 399 and continue: 3997 / 728

On to step 6:
728 can be fit into 3997 5 times, resulting in a remainder of 357.
The next digit of our result is 5. 
Result so far: 215.0
Deduct 3640 from 3997 and we're left with 357.
Bring next digit (7) of the dividend behind the 357 and repeat the process: 3577 / 728

Going ahead to step 7:
728 can be fit into 3577 4 times, resulting in a remainder of 665.
The next digit of our result is 4. 
Result so far: 2154.0
Deduct 2912 from 3577 and we're left with 665.
Append the next digit (6) from the dividend to 665 and continue with: 6656 / 728

Step 8:
728 goes into 6656 9 times with a remainder of 104.
The next digit of our result is 9. 
Result so far: 21549.0
The remainder is 104 after subtracting 6552 from 6656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 9:
The number 728 fits into 1040 1 times, leaving a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 21549.1
If we take 728 away from 1040, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 10:
728 can be fit into 3120 4 times, resulting in a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 21549.14
If we subtract 2912 from 3120, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
728 can be fit into 2080 2 times, resulting in a remainder of 624.
The number 2 becomes the next digit in our result. 
Result so far: 21549.142
If we take 1456 away from 2080, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 12:
6240 divided by 728 is 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 21549.1428
Subtract 5824 from 6240 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 13:
If we divide 4160 by 728, we get 5 and a remainder of 520.
The next digit of our result is 5. 
Result so far: 21549.14285
Subtract 3640 from 4160 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 14:
728 goes into 5200 7 times with a remainder of 104.
The number 7 becomes the next digit in our result. 
Result so far: 21549.142857
If we take 5096 away from 5200, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 15:
728 can be fit into 1040 1 times, resulting in a remainder of 312.
Write down 1 as next digit of the result. 
Result so far: 21549.1428571
Subtract 728 from 1040 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 16:
728 can be fit into 3120 4 times, resulting in a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 21549.14285714
Subtracting 2912 from 3120 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

In conclusion, the division gives 21549.14285714 with a balance of 2.08e-07.
