Let's divide 859310 by 3
We want to figure out the number of times 859310 can be divided by 3.

Moving on to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Going ahead to step 2:
3 goes into 25 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 1 after subtracting 24 from 25.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

On to step 3:
19 divided by 3 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
If we take 18 away from 19, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Going ahead to step 4:
3 goes into 13 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 2864.0
Subtracting 12 from 13 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Moving on to step 5:
3 goes into 11 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 28643.0
The remainder is 2 after subtracting 9 from 11.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Step 6:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 286436.0
Deduct 18 from 20 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.

Moving on to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 286436.6
Subtracting 18 from 20 leaves us 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.

Moving on to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 286436.66
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.

Our division results in 286436.66 with a remaining 0.002.
