Bacteria divide by binary fission which simply means that one cell splits in two. As a separate matter, there is a process called conjugation for transfer of genetic information that is completely different than binary fission. The bacterial organism would then start to divide and multiply. Some bacteria can form spores when it cannot survive very well (such as in freezing temperature) and then take off the spore barrier when multiplication and feeding conditions are better.
