799189 divided by 80 
Let's see how many times 80 fits into 799189.

Moving on to step 1:
7 divided by 80 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 80

Let's proceed 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 take 0 away from 79, we end up with 79.
Grab the next digit (9) from the dividend, add it to 79, then carry on: 799 / 80

On to step 3:
The number 80 fits into 799 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 720 from 799 to get 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 80

On to step 4:
The number 80 fits into 791 9 times, leaving a remainder of 71.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 720 from 791 and we're left with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 80

On to step 5:
80 can be fit into 718 8 times, resulting in a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 998.0
If we take 640 away from 718, we end up with 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 80

Advancing to step 6:
When dividing 789 by 80, we get 9 with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 9989.0
Subtract 720 from 789 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
When dividing 690 by 80, we get 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 9989.8
If we take 640 away from 690, we end up 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.

Advancing to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 9989.86
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
200 divided by 80 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 9989.862
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9989.8625
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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9989.8625
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.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9989.8625
If we subtract 0 from 0, we 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.

After the division, we end up with 9989.8625 and a remainder of 0.0.
