799609 divided by 80 
Our goal is to divide 799609 by 80.

Let's proceed to step 1:
7 divided by 80 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 80

On to step 2:
80 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 80

Going ahead to step 3:
799 divided by 80 is 9 with a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 720 away from 799, we end up with 79.
Bring next digit (6) of the dividend behind the 79 and repeat the process: 796 / 80

Going ahead to step 4:
796 divided by 80 is 9 with a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 720 from 796 leaves us with 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 80

Going ahead to step 5:
When dividing 760 by 80, we get 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 999.0
Subtracting 720 from 760 leaves us with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 80

Moving on to step 6:
If we divide 409 by 80, we get 5 and a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 9995.0
Subtracting 400 from 409 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 80 fits into 90 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 9995.1
If we take 80 away from 90, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 9995.11
Subtracting 80 from 100 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.

The final outcome is 9995.11, with a leftover of 0.02.
