543113 ÷ 80 
Our goal is to divide 543113 by 80.

Moving on to step 1:
80 goes into 5 0 times with 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.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 80

Step 2:
80 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 80

Step 3:
80 goes into 543 6 times with a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 480 from 543, we get 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 80

On to step 4:
The number 80 fits into 631 7 times, leaving 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 (1) from the dividend and append it to 71, then repeat: 711 / 80

Step 5:
When dividing 711 by 80, we get 8 with a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 678.0
If we subtract 640 from 711, we get 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 80

Going ahead to step 6:
The number 80 fits into 713 8 times, leaving a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 6788.0
Subtract 640 from 713 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
730 divided by 80 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 6788.9
Subtract 720 from 730 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 6788.91
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 6788.912
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6788.9125
Deduct 400 from 400 and we're left 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 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6788.9125
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.

Step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6788.9125
Deduct 0 from 0 and we're left 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 quotient of the division is 6788.9125, and the remainder is 0.0.
