865311 divided by 80 
We want to figure out the number of times 865311 can be divided by 80.

Step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 80

Let's proceed to step 2:
If we divide 86 by 80, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 6 after subtracting 80 from 86.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 80

Going ahead to step 3:
65 divided by 80 is 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 80

Let's proceed to step 4:
653 divided by 80 is 8 with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we subtract 640 from 653, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 80

On to step 5:
If we divide 131 by 80, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1081.0
Deduct 80 from 131 and we're left with 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 80

Going ahead to step 6:
The number 80 fits into 511 6 times, leaving a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 10816.0
Subtracting 480 from 511 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
80 goes into 310 3 times with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 10816.3
The remainder is 70 after subtracting 240 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 10816.38
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10816.387
Deduct 560 from 600 and we're left 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.

Advancing to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10816.3875
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.

On to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10816.3875
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.

Going ahead 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: 10816.3875
If we subtract 0 from 0, we 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.

After the division, we end up with 10816.3875 and a remainder of 0.0.
