578972 ÷ 80 
We're looking to find how many times 80 goes into 578972.

Advancing to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 80

Advancing to step 2:
80 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 80

Step 3:
If we divide 578 by 80, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 18 after subtracting 560 from 578.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 80

Moving on to step 4:
When dividing 189 by 80, we get 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 160 from 189 to get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 80

Advancing to step 5:
The number 80 fits into 297 3 times, leaving a remainder of 57.
The next digit of our result is 3. 
Result so far: 723.0
Subtract 240 from 297 to get 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 80

Going ahead to step 6:
When dividing 572 by 80, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7237.0
Subtracting 560 from 572 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
80 can be fit into 120 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 7237.1
The remainder is 40 after subtracting 80 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 7237.15
If we subtract 400 from 400, 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 9:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7237.15
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.

Let's proceed to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7237.15
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 7237.15, with a leftover of 0.0.
