We look at the division of 860288 by 3 
We're looking to find how many times 3 goes into 860288.

Advancing to step 1:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

On to step 2:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

Step 3:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
Subtracting 18 from 20 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Moving on to step 4:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 2867.0
Subtract 21 from 22 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Step 5:
18 divided by 3 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 28676.0
If we take 18 away from 18, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Moving on to step 6:
If we divide 8 by 3, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 286762.0
Deduct 6 from 8 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 286762.6
Subtract 18 from 20 to 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.

Advancing to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 286762.66
If we take 18 away from 20, we end up with 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 286762.66 with a balance of 0.002.
