We look at the division of 77140728 by 721 
We want to figure out the number of times 77140728 can be divided by 721.

Going ahead to step 1:
The number 721 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.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 721

Step 2:
If we divide 77 by 721, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 721

Let's proceed to step 3:
The number 721 fits into 771 1 times, leaving a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 721 from 771, we get 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 721

Let's proceed to step 4:
When dividing 504 by 721, we get 0 with a remainder of 504.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 504, we get 504.
Include the next digit (0) from the dividend after 504, then repeat: 5040 / 721

Going ahead to step 5:
If we divide 5040 by 721, we get 6 and a remainder of 714.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we subtract 4326 from 5040, we get 714.
Bring next digit (7) of the dividend behind the 714 and repeat the process: 7147 / 721

Moving on to step 6:
721 can be fit into 7147 9 times, resulting in a remainder of 658.
Use 9 as the next digit of our solution. 
Result so far: 1069.0
Subtracting 6489 from 7147 leaves us with 658.
Bring next digit (2) of the dividend behind the 658 and repeat the process: 6582 / 721

On to step 7:
721 goes into 6582 9 times with a remainder of 93.
The number 9 becomes the next digit in our result. 
Result so far: 10699.0
Deduct 6489 from 6582 and we're left with 93.
Fetch the next digit (8) from the dividend, attach it to 93 and continue: 938 / 721

Step 8:
721 can be fit into 938 1 times, resulting in a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 106991.0
Deduct 721 from 938 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 9:
The number 721 fits into 2170 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 106991.3
Deduct 2163 from 2170 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
If we divide 70 by 721, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 106991.3
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
721 can be fit into 700 0 times, resulting in a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 106991.3
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 106991.3 with a balance of 0.07.
