Let's divide 866274 by 80
Our goal is to divide 866274 by 80.

Moving on to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 80

Going ahead to step 2:
80 goes into 86 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 86 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 80

Going ahead to step 3:
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: 10.0
If we take 0 away from 66, we end up with 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 80

Advancing to step 4:
If we divide 662 by 80, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 640 from 662 leaves us with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 80

Step 5:
The number 80 fits into 227 2 times, leaving a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 1082.0
If we subtract 160 from 227, we get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 80

Let's proceed to step 6:
When dividing 674 by 80, we get 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 10828.0
If we take 640 away from 674, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
80 can be fit into 340 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 10828.4
If we take 320 away from 340, we end up 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.

Advancing to step 8:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 10828.42
If we take 160 away from 200, we end up 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.

Let's proceed to step 9:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10828.425
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.

Advancing to step 10:
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: 10828.425
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.

Let's proceed to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10828.425
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 result is 10828.425 with a remainder of 0.0.
