321568 ÷ 80 
We're looking to find how many times 80 goes into 321568.

Step 1:
80 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 80

On to step 2:
The number 80 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 80

Step 3:
321 divided by 80 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 320 away from 321, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 80

On to step 4:
The number 80 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 80

Moving on to step 5:
When dividing 156 by 80, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 401.0
If we take 80 away from 156, we end up with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 80

On to step 6:
80 can be fit into 768 9 times, resulting in a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 4019.0
The remainder is 48 after subtracting 720 from 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
When dividing 480 by 80, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 4019.6
The remainder is 0 after subtracting 480 from 480.
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.
The next digit of our result is 0. 
Result so far: 4019.6
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.

Advancing to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4019.6
Subtract 0 from 0 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.

In conclusion, the division gives 4019.6 with a balance of 0.0.
