543120 ÷ 80 
We want to divide 543120 by 80.

Moving on 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
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 80

Step 2:
If we divide 54 by 80, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 80

Moving on to step 3:
The number 80 fits into 543 6 times, leaving a remainder of 63.
The next digit of our result is 6. 
Result so far: 6.0
If we take 480 away from 543, we end up with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 80

Advancing to step 4:
When dividing 631 by 80, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 67.0
The remainder is 71 after subtracting 560 from 631.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 80

Going ahead to step 5:
80 can be fit into 712 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 678.0
Subtract 640 from 712 to get 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 80

Let's proceed to step 6:
80 can be fit into 720 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 6789.0
The remainder is 0 after subtracting 720 from 720.
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 7:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6789.0
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.

Going ahead to step 8:
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: 6789.0
Subtracting 0 from 0 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.

In conclusion, the division gives 6789.0 with a balance of 0.0.
