We look at the division of 836291 by 3 
Let's see how many times 3 fits into 836291.

Let's proceed to step 1:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Advancing to step 2:
3 goes into 23 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Moving on to step 3:
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: 278.0
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

On to step 4:
3 goes into 22 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 2787.0
Subtracting 21 from 22 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

On to step 5:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 27876.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Moving on to step 6:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 278763.0
Subtract 9 from 11 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.

Step 7:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 278763.6
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.

Let's proceed to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 278763.66
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.

The final result is 278763.66 with a remainder of 0.002.
