Tom Riddle had figured out how to split off one-seventh of his soul immediately, and he decided to do that after the death of Myrtle. He messed up in his calculations, however, and left only one-seventh in his body. He made Abraxas Malfoy into a Dark Lord, with his diary guiding him and that one-seventh of a soul possessing Malfoy. When Malfoy attempted to kill an infant Harry Potter after his parents, the spell rebounded and transferred Riddle's soul shard to Harry. Lucius kept the diary, before he develops a nefarious plan for Potter's Fifth Year,

That's all small potatoes to Harry, though. He's gay in a world that will never, never accept him, and now, his new diary doesn't just write back, a very attractive boy lives in it.
