Let's divide 666827 by 80
We're looking to find how many times 80 goes into 666827.

Going ahead to step 1:
6 divided by 80 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 80

Moving on to step 2:
80 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 80

Step 3:
80 can be fit into 666 8 times, resulting in a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 640 away from 666, we end up with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 80

Step 4:
80 can be fit into 268 3 times, resulting in a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtracting 240 from 268 leaves us with 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 80

Moving on to step 5:
If we divide 282 by 80, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 833.0
Subtracting 240 from 282 leaves us with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 80

Advancing to step 6:
80 goes into 427 5 times with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 8335.0
The remainder is 27 after subtracting 400 from 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
The number 80 fits into 270 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 8335.3
If we take 240 away from 270, we end up 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.

On to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 8335.33
Subtracting 240 from 300 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.

The final result is 8335.33 with a remainder of 0.06.
