Let's divide 666801 by 80
Our goal is to divide 666801 by 80.

Advancing to step 1:
80 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 80

Advancing to step 2:
80 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 80

Going ahead to step 3:
When dividing 666 by 80, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 640 away from 666, we end up with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 80

Moving on to step 4:
The number 80 fits into 268 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
The remainder is 28 after subtracting 240 from 268.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 80

Moving on to step 5:
The number 80 fits into 280 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 833.0
The remainder is 40 after subtracting 240 from 280.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 80

On to step 6:
If we divide 401 by 80, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 8335.0
Subtract 400 from 401 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 80, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8335.0
If we subtract 0 from 10, we 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.

Step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 8335.01
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 goes into 200 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 8335.012
Subtracting 160 from 200 leaves us 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.

Moving on to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8335.0125
Subtracting 400 from 400 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 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8335.0125
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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8335.0125
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.

In conclusion, the division gives 8335.0125 with a balance of 0.0.
