We're dividing 864085 by 10 
Let's see how many times 10 fits into 864085.

Advancing to step 1:
8 divided by 10 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 10

Step 2:
The number 10 fits into 86 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 80 away from 86, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 10

Moving on to step 3:
10 can be fit into 64 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we subtract 60 from 64, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 10

On to step 4:
If we divide 40 by 10, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 864.0
If we take 40 away from 40, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 10

On to step 5:
8 divided by 10 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 8640.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 10

On to step 6:
10 can be fit into 85 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 86408.0
Subtract 80 from 85 to get 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:
The number 10 fits into 50 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 86408.5
Deduct 50 from 50 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.

Moving on to step 8:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 86408.5
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.

Step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 86408.5
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.

In conclusion, the division gives 86408.5 with a balance of 0.0.
