We're dividing 864893 by 80 
We want to figure out the number of times 864893 can be divided by 80.

Advancing to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 80

Step 2:
The number 80 fits into 86 1 times, leaving 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 80

Let's proceed to step 3:
64 divided by 80 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 64, we get 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 80

On to step 4:
648 divided by 80 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 8 after subtracting 640 from 648.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 80

Going ahead to step 5:
When dividing 89 by 80, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1081.0
Subtract 80 from 89 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 80

Advancing to step 6:
When dividing 93 by 80, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 10811.0
Deduct 80 from 93 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 80, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 10811.1
Deduct 80 from 130 and we're left 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.

Moving on to step 8:
500 divided by 80 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 10811.16
If we take 480 away from 500, 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.

Going ahead to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 10811.162
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.

Advancing to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10811.1625
If we subtract 400 from 400, 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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10811.1625
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10811.1625
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.

The final result is 10811.1625 with a remainder of 0.0.
