We're dividing 78391587 by 720 
We want to figure out the number of times 78391587 can be divided by 720.

Going ahead to step 1:
The number 720 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 720

Going ahead to step 2:
If we divide 78 by 720, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 720

Going ahead to step 3:
720 goes into 783 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 720 from 783 leaves us with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 720

Moving on to step 4:
720 can be fit into 639 0 times, resulting in a remainder of 639.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 639 to get 639.
Fetch the next digit (1) from the dividend, attach it to 639 and continue: 6391 / 720

Moving on to step 5:
720 can be fit into 6391 8 times, resulting in a remainder of 631.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtract 5760 from 6391 to get 631.
Append the next digit (5) from the dividend to 631 and continue with: 6315 / 720

Let's proceed to step 6:
The number 720 fits into 6315 8 times, leaving a remainder of 555.
The next digit of our result is 8. 
Result so far: 1088.0
Subtract 5760 from 6315 to get 555.
Take the next digit (8) from the dividend and append it to 555, then repeat: 5558 / 720

On to step 7:
5558 divided by 720 is 7 with a remainder of 518.
The next digit of our result is 7. 
Result so far: 10887.0
Subtracting 5040 from 5558 leaves us with 518.
Include the next digit (7) from the dividend after 518, then repeat: 5187 / 720

Moving on to step 8:
When dividing 5187 by 720, we get 7 with a remainder of 147.
The next digit of our result is 7. 
Result so far: 108877.0
Subtracting 5040 from 5187 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 9:
720 goes into 1470 2 times with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 108877.2
Subtracting 1440 from 1470 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
720 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 108877.2
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
3000 divided by 720 is 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 108877.204
The remainder is 120 after subtracting 2880 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
1200 divided by 720 is 1 with a remainder of 480.
The next digit of our result is 1. 
Result so far: 108877.2041
Subtracting 720 from 1200 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
If we divide 4800 by 720, we get 6 and a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 108877.20416
Subtracting 4320 from 4800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
4800 divided by 720 is 6 with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 108877.204166
If we take 4320 away from 4800, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 108877.204166 with a balance of 4.8e-05.
