We divide 857360 by 80
Our goal is to divide 857360 by 80.

Moving on to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 80

On to step 2:
The number 80 fits into 85 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 80 from 85.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 80

Moving on to step 3:
80 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 57, we get 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 80

Moving on to step 4:
If we divide 573 by 80, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we subtract 560 from 573, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 80

Moving on to step 5:
The number 80 fits into 136 1 times, leaving a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1071.0
Subtracting 80 from 136 leaves us with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 80

Going ahead to step 6:
560 divided by 80 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 10717.0
Subtract 560 from 560 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 7:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10717.0
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.

Step 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10717.0
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.

The quotient of the division is 10717.0, and the remainder is 0.0.
