We divide 780597 by 80
Let's see how many times 80 fits into 780597.

Step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 80

Going ahead to step 2:
If we divide 78 by 80, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 80

On to step 3:
When dividing 780 by 80, we get 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 720 from 780 leaves us with 60.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 80

Advancing to step 4:
80 goes into 605 7 times with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 560 from 605 to get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 80

On to step 5:
459 divided by 80 is 5 with a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 975.0
Subtract 400 from 459 to get 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 80

On to step 6:
The number 80 fits into 597 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 9757.0
The remainder is 37 after subtracting 560 from 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
80 can be fit into 370 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 9757.4
The remainder is 50 after subtracting 320 from 370.
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:
500 divided by 80 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 9757.46
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.

On to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 9757.462
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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9757.4625
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.

Moving on to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9757.4625
Subtract 0 from 0 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.

Advancing to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9757.4625
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.

After the division, we end up with 9757.4625 and a remainder of 0.0.
