We divide 7864721 by 728
We want to divide 7864721 by 728.

Step 1:
When dividing 7 by 728, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 728

On to step 2:
If we divide 78 by 728, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 728

Step 3:
The number 728 fits into 786 1 times, leaving a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 58 after subtracting 728 from 786.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 728

Advancing to step 4:
The number 728 fits into 584 0 times, leaving a remainder of 584.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 584, we get 584.
Take the next digit (7) from the dividend and append it to 584, then repeat: 5847 / 728

Step 5:
728 goes into 5847 8 times with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtracting 5824 from 5847 leaves us with 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 728

Going ahead to step 6:
When dividing 232 by 728, we get 0 with a remainder of 232.
Put 0 as the next digit of the answer. 
Result so far: 1080.0
If we take 0 away from 232, we end up with 232.
Append the next digit (1) from the dividend to 232 and continue with: 2321 / 728

Moving on to step 7:
The number 728 fits into 2321 3 times, leaving a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 10803.0
Subtract 2184 from 2321 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 8:
When dividing 1370 by 728, we get 1 with a remainder of 642.
Put 1 as the next digit of the answer. 
Result so far: 10803.1
Subtracting 728 from 1370 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Step 9:
If we divide 6420 by 728, we get 8 and a remainder of 596.
The next digit of our result is 8. 
Result so far: 10803.18
Deduct 5824 from 6420 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 10:
5960 divided by 728 is 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 10803.188
Subtracting 5824 from 5960 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 10803.188, and the remainder is 0.0136.
