We divide 770429 by 80
We're looking to find how many times 80 goes into 770429.

Moving on to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 80

Advancing to step 2:
80 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 80

Let's proceed to step 3:
If we divide 770 by 80, we get 9 and a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 720 from 770, we get 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 80

Step 4:
If we divide 504 by 80, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtracting 480 from 504 leaves us with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 80

Step 5:
If we divide 242 by 80, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 963.0
Subtract 240 from 242 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 80

On to step 6:
When dividing 29 by 80, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 9630.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
80 goes into 290 3 times with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 9630.3
If we take 240 away from 290, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 9630.36
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9630.362
If we take 160 away from 200, we end up 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.

Let's proceed to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9630.3625
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9630.3625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9630.3625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 9630.3625 with a balance of 0.0.
