We look at the division of 77229715 by 774 
We're looking to find how many times 774 goes into 77229715.

Step 1:
774 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 774

Let's proceed to step 2:
774 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 774

Going ahead to step 3:
774 goes into 772 0 times with a remainder of 772.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 772 after subtracting 0 from 772.
Take the next digit (2) from the dividend and append it to 772, then repeat: 7722 / 774

Let's proceed to step 4:
The number 774 fits into 7722 9 times, leaving a remainder of 756.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 6966 from 7722 and we're left with 756.
Bring next digit (9) of the dividend behind the 756 and repeat the process: 7569 / 774

On to step 5:
7569 divided by 774 is 9 with a remainder of 603.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 6966 from 7569 to get 603.
Append the next digit (7) from the dividend to 603 and continue with: 6037 / 774

Let's proceed to step 6:
774 can be fit into 6037 7 times, resulting in a remainder of 619.
The next digit of our result is 7. 
Result so far: 997.0
Subtracting 5418 from 6037 leaves us with 619.
Include the next digit (1) from the dividend after 619, then repeat: 6191 / 774

Going ahead to step 7:
When dividing 6191 by 774, we get 7 with a remainder of 773.
The next digit of our result is 7. 
Result so far: 9977.0
Subtract 5418 from 6191 to get 773.
Append the next digit (5) from the dividend to 773 and continue with: 7735 / 774

Let's proceed to step 8:
If we divide 7735 by 774, we get 9 and a remainder of 769.
Write down 9 as next digit of the result. 
Result so far: 99779.0
Deduct 6966 from 7735 and we're left with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Going ahead to step 9:
7690 divided by 774 is 9 with a remainder of 724.
Record the quotient 9 as the next digit in the result. 
Result so far: 99779.9
Subtracting 6966 from 7690 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Moving on to step 10:
When dividing 7240 by 774, we get 9 with a remainder of 274.
Record the quotient 9 as the next digit in the result. 
Result so far: 99779.99
If we subtract 6966 from 7240, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

In conclusion, the division gives 99779.99 with a balance of 0.274.
