540659 divided by 80 
Our goal is to divide 540659 by 80.

Step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 80

Advancing to step 2:
80 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 80

Moving on to step 3:
80 can be fit into 540 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 480 from 540 and we're left with 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 80

Moving on to step 4:
606 divided by 80 is 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtract 560 from 606 to get 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 80

Moving on to step 5:
465 divided by 80 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 675.0
The remainder is 65 after subtracting 400 from 465.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 80

On to step 6:
80 can be fit into 659 8 times, resulting in a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 6758.0
Subtract 640 from 659 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
80 goes into 190 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 6758.2
Subtracting 160 from 190 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 6758.23
Deduct 240 from 300 and we're left 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.

Let's proceed to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 6758.237
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6758.2375
If we take 400 away from 400, 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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6758.2375
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.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6758.2375
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.

In conclusion, the division gives 6758.2375 with a balance of 0.0.
