79820721 ÷ 728 
Let's see how many times 728 fits into 79820721.

Going ahead to step 1:
728 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 728

Advancing to step 2:
If we divide 79 by 728, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 728

Advancing to step 3:
728 can be fit into 798 1 times, resulting in a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 70 after subtracting 728 from 798.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 728

On to step 4:
728 goes into 702 0 times with a remainder of 702.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 702 leaves us with 702.
Take the next digit (0) from the dividend and append it to 702, then repeat: 7020 / 728

Going ahead to step 5:
If we divide 7020 by 728, we get 9 and a remainder of 468.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 6552 away from 7020, we end up with 468.
Append the next digit (7) from the dividend to 468 and continue with: 4687 / 728

Going ahead to step 6:
The number 728 fits into 4687 6 times, leaving a remainder of 319.
The next digit of our result is 6. 
Result so far: 1096.0
If we take 4368 away from 4687, we end up with 319.
Take the next digit (2) from the dividend and append it to 319, then repeat: 3192 / 728

On to step 7:
3192 divided by 728 is 4 with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 10964.0
The remainder is 280 after subtracting 2912 from 3192.
Take the next digit (1) from the dividend and append it to 280, then repeat: 2801 / 728

Moving on to step 8:
728 goes into 2801 3 times with a remainder of 617.
The next digit of our result is 3. 
Result so far: 109643.0
If we subtract 2184 from 2801, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Going ahead to step 9:
When dividing 6170 by 728, we get 8 with a remainder of 346.
Write down 8 as next digit of the result. 
Result so far: 109643.8
Subtracting 5824 from 6170 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 10:
3460 divided by 728 is 4 with a remainder of 548.
Record the quotient 4 as the next digit in the result. 
Result so far: 109643.84
The remainder is 548 after subtracting 2912 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
5480 divided by 728 is 7 with a remainder of 384.
Write down 7 as next digit of the result. 
Result so far: 109643.847
The remainder is 384 after subtracting 5096 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 12:
3840 divided by 728 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 109643.8475
If we take 3640 away from 3840, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
When dividing 2000 by 728, we get 2 with a remainder of 544.
Use 2 as the next digit of our solution. 
Result so far: 109643.84752
If we subtract 1456 from 2000, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 14:
When dividing 5440 by 728, we get 7 with a remainder of 344.
The next digit of our result is 7. 
Result so far: 109643.847527
Deduct 5096 from 5440 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 15:
If we divide 3440 by 728, we get 4 and a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 109643.8475274
If we take 2912 away from 3440, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 16:
5280 divided by 728 is 7 with a remainder of 184.
Use 7 as the next digit of our solution. 
Result so far: 109643.84752747
Deduct 5096 from 5280 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 109643.84752747, and the remainder is 1.84e-07.
