How can a day be longer than a year?

Venus takes 224.7 Earth days to revolve about the Sun and 243.02 Earth days to rotate about its axis (which it does clockwise, opposite to most of the other planets). This rotation period is a "sidereal day", the time to revolve around the Sun is a Venus "year". Mercury takes 88 Earth days to go around the Sun, so its year is 88 Earth days. It spins slowly, taking 58.6 Earth days. A "solar day" on Mercury takes 176 Earth days because of this slow spin relative to the time taken to orbit. So Venus has a sidereal day longer than its year and Mercury has a solar day longer than its year.

What planet spins most slowly?

Venus spins the most slowly of any planet in our solar system. It takes 243 Earth days to complete one rotation on its axis, which is longer than the time it takes for Venus to complete one orbit around the Sun.
