We're dividing 911639 by 3 
We're looking to find how many times 3 goes into 911639.

Moving on to step 1:
If we divide 9 by 3, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Going ahead to step 2:
If we divide 1 by 3, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 1, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Let's proceed to step 3:
The number 3 fits into 11 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 303.0
Deduct 9 from 11 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Advancing to step 4:
26 divided by 3 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3038.0
Subtracting 24 from 26 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Step 5:
23 divided by 3 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 30387.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

Moving on to step 6:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 303879.0
Subtracting 27 from 29 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.

Step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 303879.6
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.

Let's proceed to step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 303879.66
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.

The final result is 303879.66 with a remainder of 0.002.
