We're dividing 866085 by 80 
Our goal is to divide 866085 by 80.

Advancing to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 80

Moving on to step 2:
80 can be fit into 86 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 80 from 86.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 80

Going ahead to step 3:
If we divide 66 by 80, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 66, we get 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 80

Going ahead to step 4:
The number 80 fits into 660 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we subtract 640 from 660, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 80

Step 5:
208 divided by 80 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1082.0
If we subtract 160 from 208, we get 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 80

Moving on to step 6:
If we divide 485 by 80, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 10826.0
Subtracting 480 from 485 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
80 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10826.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 10826.06
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 10826.062
If we subtract 160 from 200, 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.

Advancing to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10826.0625
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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10826.0625
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.

Moving on to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10826.0625
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 10826.0625 with a balance of 0.0.
