865854 ÷ 80 
We're looking to find how many times 80 goes into 865854.

Let's proceed to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 80

Going ahead to step 2:
The number 80 fits into 86 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 86 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 80

Going ahead to step 3:
The number 80 fits into 65 0 times, leaving a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 65 after subtracting 0 from 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 80

Going ahead to step 4:
80 goes into 658 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtract 640 from 658 to get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 80

Let's proceed to step 5:
185 divided by 80 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 1082.0
If we subtract 160 from 185, we get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 80

Going ahead to step 6:
80 goes into 254 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 10823.0
Subtract 240 from 254 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 80 is 1 with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 10823.1
Subtracting 80 from 140 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.

Going ahead to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 10823.17
If we take 560 away from 600, 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.

Moving on to step 9:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10823.175
Subtract 400 from 400 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.

Going ahead to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10823.175
Subtracting 0 from 0 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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10823.175
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 quotient of the division is 10823.175, and the remainder is 0.0.
