We look at the division of 863534 by 3 
Let's see how many times 3 fits into 863534.

Advancing to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

On to step 2:
If we divide 26 by 3, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Step 3:
23 divided by 3 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
If we take 21 away from 23, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Going ahead to step 4:
25 divided by 3 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 2878.0
If we take 24 away from 25, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

On to step 5:
3 goes into 13 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 28784.0
Deduct 12 from 13 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Advancing to step 6:
When dividing 14 by 3, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 287844.0
If we subtract 12 from 14, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 287844.6
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 287844.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 287844.66 with a balance of 0.002.
