You can defo use playing cards for divination - there're a lot of theories about whether Tarot developed from playing cards or vice versa, but one way or another, they're related to some extent.
You can use systems other folks have developed, such as the one Lycaon linked to, but it's also possible to make your own system up, provided you're comfortable with making symbol systems that link to one another. The whole idea behind Tarot is that the cards represent multiple isomorphims, which is to say that it can be mapped between more than one symbol system. For example, the cards of the Thoth Tarot can be mapped to the planets, but they can also linked to the Hebrew alphabet, the I Ching, the Tree of Life/Kabbalah and so on. If you're comfy with making your own connections between the cards and other established systems (or not - you can map them directly to life situations), you're good to go. For example, the person in Lyc's link has mapped Wands to Clubs, which in turn are mapped to social situations, Swords to Spades which map to rationale, etc etc.
