We're dividing 862429 by 3 
Let's see how many times 3 fits into 862429.

Let's proceed to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Let's proceed to step 2:
If we divide 26 by 3, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 24 from 26, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Going ahead to step 3:
22 divided by 3 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Deduct 21 from 22 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Let's proceed to step 4:
When dividing 14 by 3, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 2874.0
Deduct 12 from 14 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

On to step 5:
When dividing 22 by 3, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 28747.0
Subtract 21 from 22 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Moving on to step 6:
19 divided by 3 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 287476.0
If we subtract 18 from 19, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 287476.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 287476.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 287476.33 with a remaining 0.001.
