We divide 783573 by 80
We're looking to find how many times 80 goes into 783573.

Going ahead to step 1:
80 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 80

Step 2:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 80

Advancing to step 3:
80 can be fit into 783 9 times, resulting in a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 63 after subtracting 720 from 783.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 80

Going ahead to step 4:
80 goes into 635 7 times with a remainder of 75.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 75 after subtracting 560 from 635.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 80

Let's proceed to step 5:
When dividing 757 by 80, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 979.0
Subtracting 720 from 757 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 80

Step 6:
When dividing 373 by 80, we get 4 with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 9794.0
Subtracting 320 from 373 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
When dividing 530 by 80, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 9794.6
Subtracting 480 from 530 leaves us 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.

On to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 9794.66
If we subtract 480 from 500, 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.

The final result is 9794.66 with a remainder of 0.02.
