We're dividing 862838 by 3 
Our goal is to divide 862838 by 3.

Step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Going ahead to step 2:
The number 3 fits into 26 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 2 after subtracting 24 from 26.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Advancing to step 3:
When dividing 22 by 3, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
The remainder is 1 after subtracting 21 from 22.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Advancing to step 4:
18 divided by 3 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2876.0
Subtract 18 from 18 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

Let's proceed to step 5:
If we divide 3 by 3, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 28761.0
If we take 3 away from 3, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

On to step 6:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 287612.0
If we subtract 6 from 8, 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.

Step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 287612.6
The remainder is 2 after subtracting 18 from 20.
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:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 287612.66
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.

The final outcome is 287612.66, with a leftover of 0.002.
