Let's divide 543503 by 80
We want to divide 543503 by 80.

Step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 80

Advancing to step 2:
80 goes into 54 0 times with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 80

Moving on to step 3:
When dividing 543 by 80, we get 6 with 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.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 80

Advancing to step 4:
635 divided by 80 is 7 with a remainder of 75.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 560 from 635 leaves us with 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 80

Let's proceed to step 5:
When dividing 750 by 80, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 679.0
Subtract 720 from 750 to get 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 80

Step 6:
The number 80 fits into 303 3 times, leaving a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 6793.0
Subtract 240 from 303 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
The number 80 fits into 630 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 6793.7
The remainder is 70 after subtracting 560 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
80 goes into 700 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 6793.78
Subtracting 640 from 700 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.

Going ahead to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 6793.787
Deduct 560 from 600 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.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6793.7875
Subtract 400 from 400 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.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6793.7875
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 12:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6793.7875
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.

In conclusion, the division gives 6793.7875 with a balance of 0.0.
