If you have a large gap beneath the door, use a wrap-around door sweep. They have long adjustable sides that can be moved up and down along the width of the door. When the bottom of the sweep fills in the door gap, drill pilot holes through the sides and screw it down. Put in a door threshold.
Also, how do you seal a gap between double doors? Double doors often require a hardware device known as an "astragal."

If the gap is less than 1/2 inch wide, you can fill it with acrylic latex caulk. If it's wider than that, caulk won't bind well, and you should use polyurethane foam instead. Use the least dense foam you can find so that the connection between the jamb and the framing remains flexible.
