728977 divided by 87 
We want to figure out the number of times 728977 can be divided by 87.

Advancing to step 1:
87 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 87

Step 2:
The number 87 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 87

Advancing to step 3:
When dividing 728 by 87, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 32 after subtracting 696 from 728.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 87

On to step 4:
87 can be fit into 329 3 times, resulting in a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we subtract 261 from 329, we get 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 87

Step 5:
87 can be fit into 687 7 times, resulting in a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 837.0
If we take 609 away from 687, we end up with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 87

Moving on to step 6:
787 divided by 87 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 8379.0
The remainder is 4 after subtracting 783 from 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
The number 87 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8379.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 87, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 8379.04
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
87 goes into 520 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 8379.045
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 10:
850 divided by 87 is 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 8379.0459
Deduct 783 from 850 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
87 can be fit into 670 7 times, resulting in a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 8379.04597
Subtracting 609 from 670 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
When dividing 610 by 87, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 8379.045977
If we subtract 609 from 610, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 8379.045977 and a remainder of 1e-07.
