780177 ÷ 80 
Let's see how many times 80 fits into 780177.

On to step 1:
80 can be fit into 7 0 times, resulting in 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.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 80

Going ahead to step 2:
When dividing 78 by 80, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 80

Moving on to step 3:
80 goes into 780 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 720 from 780 leaves us with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 80

Advancing to step 4:
601 divided by 80 is 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 560 from 601, we get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 80

Going ahead to step 5:
When dividing 417 by 80, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 975.0
If we subtract 400 from 417, we get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 80

On to step 6:
80 goes into 177 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 9752.0
If we subtract 160 from 177, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 80 fits into 170 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 9752.2
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 9752.21
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9752.212
Subtracting 160 from 200 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 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9752.2125
Subtract 400 from 400 to 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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9752.2125
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.

Moving on to step 12:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9752.2125
If we subtract 0 from 0, 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.

After the division, we end up with 9752.2125 and a remainder of 0.0.
