So for example. You have a flush draw on the Flop. That gives you 9 cards to complete it. Without looking at a calculator, you have 9 * 4 = 36% to complete it by the end of the hand. If you get to the Turn and you don't have your Flush, now you have 9 * 2 = 18% to complete it on the River. These won't be the exact percentages, but they will be 23% away from the real ones so they're good enough. Obviously, making this flush won't mean you win the hand.
This is a very quick way to calculate your odds of completing a given hand. Then you need to compare it with your pot odds and/or implied odds. That's more complicated and I don't think there's an easy way to do it without experience or calculators.

the rule of 2 and 4 is a very good tool for calculating your odds quickly. however, there is an error that many players make when using this shortcut and that is: using the rule of 4 incorrectly.
the only time you want to use the rule of 4 is when you are guaranteed to see the river card, other wise you will use the rule of 2. for example, if you have a flush draw w/ 2 overcards to the flop and villain puts you allin on the flop. if you were to call the allin, you would use the rule of 4 because you are guaranteed to see the river card as there is no more betting and no chance of you folding.
however, if you have a flush draw with 2 over cards, villain bets 8 bbs into a 10 bb pot, and effective stacks is 65 bbs, then you would use the rule of 2 to figure out your odds of hitting on the turn. this is because you still have the option of folding on the turn. if you're using the rule of 4, which is the odds of hitting on the turn or river, and you don't see the river because villain bets enough to get you to fold, then you are calling with improper odds.
as a general rule: use the rule of 2 if you aren't guaranteed to see the river from the flop.
 use the rule of 2 for the odds of hitting floptoturn, and turntoriver.
 use the rule of 4 if you are guaranteed to see the river from the flop.
