We divide 81280264 by 728
We want to figure out the number of times 81280264 can be divided by 728.

Step 1:
728 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 728

On to step 2:
The number 728 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 728

On to step 3:
812 divided by 728 is 1 with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 728 from 812 and we're left with 84.
Grab the next digit (8) from the dividend, add it to 84, then carry on: 848 / 728

Moving on to step 4:
848 divided by 728 is 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 120 after subtracting 728 from 848.
Include the next digit (0) from the dividend after 120, then repeat: 1200 / 728

Step 5:
If we divide 1200 by 728, we get 1 and a remainder of 472.
Use 1 as the next digit of our solution. 
Result so far: 111.0
If we take 728 away from 1200, we end up with 472.
Include the next digit (2) from the dividend after 472, then repeat: 4722 / 728

Advancing to step 6:
4722 divided by 728 is 6 with a remainder of 354.
Record the quotient 6 as the next digit in the result. 
Result so far: 1116.0
Subtract 4368 from 4722 to get 354.
Include the next digit (6) from the dividend after 354, then repeat: 3546 / 728

Going ahead to step 7:
When dividing 3546 by 728, we get 4 with a remainder of 634.
Record the quotient 4 as the next digit in the result. 
Result so far: 11164.0
Subtracting 2912 from 3546 leaves us with 634.
Take the next digit (4) from the dividend and append it to 634, then repeat: 6344 / 728

Step 8:
The number 728 fits into 6344 8 times, leaving a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 111648.0
If we subtract 5824 from 6344, we 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.

Moving on to step 9:
The number 728 fits into 5200 7 times, leaving a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 111648.7
Subtract 5096 from 5200 to get 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 10:
The number 728 fits into 1040 1 times, leaving a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 111648.71
Deduct 728 from 1040 and we're left 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.

On to step 11:
The number 728 fits into 3120 4 times, leaving a remainder of 208.
The next digit of our result is 4. 
Result so far: 111648.714
Subtract 2912 from 3120 to 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.

Let's proceed to step 12:
The number 728 fits into 2080 2 times, leaving a remainder of 624.
Put 2 as the next digit of the answer. 
Result so far: 111648.7142
Subtract 1456 from 2080 to get 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 13:
The number 728 fits into 6240 8 times, leaving a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 111648.71428
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.

Moving on to step 14:
If we divide 4160 by 728, we get 5 and a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 111648.714285
Subtracting 3640 from 4160 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 15:
728 can be fit into 5200 7 times, resulting in a remainder of 104.
Record the quotient 7 as the next digit in the result. 
Result so far: 111648.7142857
If we subtract 5096 from 5200, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
If we divide 1040 by 728, we get 1 and a remainder of 312.
Write down 1 as next digit of the result. 
Result so far: 111648.71428571
Deduct 728 from 1040 and we're left 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.

In conclusion, the division gives 111648.71428571 with a balance of 3.12e-07.
