Let's divide 579820 by 80
We want to figure out the number of times 579820 can be divided by 80.

On to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 80

Let's proceed to step 2:
80 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 80

Advancing to step 3:
80 goes into 579 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 560 away from 579, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 80

On to step 4:
When dividing 198 by 80, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 160 from 198 leaves us with 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 80

Advancing to step 5:
If we divide 382 by 80, we get 4 and a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 724.0
If we subtract 320 from 382, we get 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 80

On to step 6:
620 divided by 80 is 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 7247.0
Subtracting 560 from 620 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
80 goes into 600 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 7247.7
The remainder is 40 after subtracting 560 from 600.
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 8:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7247.75
Subtracting 400 from 400 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 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7247.75
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.

Step 10:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7247.75
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 7247.75 and a remainder of 0.0.
