We look at the division of 516660 by 80 
Our goal is to divide 516660 by 80.

Advancing to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 80

Moving on to step 2:
80 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 80

Moving on to step 3:
80 can be fit into 516 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 480 away from 516, we end up with 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 80

Let's proceed to step 4:
366 divided by 80 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 46 after subtracting 320 from 366.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 80

Step 5:
When dividing 466 by 80, we get 5 with a remainder of 66.
The next digit of our result is 5. 
Result so far: 645.0
The remainder is 66 after subtracting 400 from 466.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 80

Moving on to step 6:
If we divide 660 by 80, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 6458.0
Deduct 640 from 660 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.

On to step 7:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 6458.2
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.

Step 8:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6458.25
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.

Step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6458.25
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.

On to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6458.25
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.

The final outcome is 6458.25, with a leftover of 0.0.
