We divide 790160 by 80
We want to figure out the number of times 790160 can be divided by 80.

Moving on to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 80

Going ahead to step 2:
If we divide 79 by 80, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 80

Going ahead to step 3:
790 divided by 80 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 720 away from 790, we end up with 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 80

Going ahead to step 4:
When dividing 701 by 80, we get 8 with a remainder of 61.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 640 from 701 leaves us with 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 80

Advancing to step 5:
If we divide 616 by 80, we get 7 and a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
Subtract 560 from 616 to get 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 80

Moving on to step 6:
80 goes into 560 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 9877.0
Subtracting 560 from 560 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.

On to step 7:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9877.0
The remainder is 0 after subtracting 0 from 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 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9877.0
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.

The final outcome is 9877.0, with a leftover of 0.0.
