We're dividing 783519 by 80 
We're looking to find how many times 80 goes into 783519.

Step 1:
If we divide 7 by 80, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 80

Advancing to step 2:
If we divide 78 by 80, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 80

On to step 3:
The number 80 fits into 783 9 times, leaving a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 720 from 783 to get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 80

Let's proceed to step 4:
635 divided by 80 is 7 with a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 560 from 635, we get 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 80

Step 5:
When dividing 751 by 80, we get 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 979.0
Subtract 720 from 751 to get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 80

Let's proceed to step 6:
80 can be fit into 319 3 times, resulting in a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 9793.0
Deduct 240 from 319 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
The number 80 fits into 790 9 times, leaving a remainder of 70.
The next digit of our result is 9. 
Result so far: 9793.9
Subtract 720 from 790 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 9793.98
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 9793.987
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9793.9875
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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9793.9875
Subtracting 0 from 0 leaves us 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.
Write down 0 as next digit of the result. 
Result so far: 9793.9875
Subtracting 0 from 0 leaves us 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 9793.9875 with a balance of 0.0.
