36009 ÷ 3 
We're looking to find how many times 3 goes into 36009.

On to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Going ahead to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Step 3:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we take 0 away from 0, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Going ahead to step 4:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1200.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

Moving on to step 5:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 12003.0
If we subtract 9 from 9, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 6:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12003.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12003.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12003.0 and a remainder of 0.0.
