The Roman Empire was never divided into two parts. Western Roman Empire and Eastern Roman Empire are terms which have been coined by historians. The Romans had only one term: Roman Empire.
The emperor Diocletian created the tetrarchy (rule by four) which had two senior emperors and two junior ones. Diocletian subdivided the empire into four praetorian prefectures which were the main administrative units of a sole empire. Each of the four emperors was in charge of one of the praetorian prefectures and was given an imperial sea. Therefore, there were four "capitals": Nicomedia (modern Izmit in north-western Turkey), Sirmium (modern Sremska Mitrovica in Serbia), Mediolanum (modern Milan in Italy) and Augusta Trevorum (modern Triers in Germany). Rome ceased to be the capital of the Roman Empire.
Constantine the Great brought the tetrarchy to an end by winning two civil wars and became the sole emperor. He decided to mark this by establishing his own imperial seat. He redeveloped Byzantium and renamed it after himself: Constantinople (which means city of Constantine). Later, Valentinian I decided to share power with his brother Valens. The two brothers became co-emperors with Valens in charge of the west and with Milan as his imperial seat, and Valens in charge of the east with Constantinople as his imperial seat. However, this was not a division of the empire. The Roman Empire had had alternations between periods of co-emperorship (with two emperors who were either father and son or brothers) and periods of sole emperorship for 113 years by then.

Constantinople was the capital of the Byzantine/Eastern Empire. It wasn't the capital of the whole empire, but it was a major city for sure.
Constantine the great built an new capital in the Eastern Roman Empire. He moved the capital form Nicomedia (in northwestern Turkey) to Constantinople.
Byzantium was a city and it was the capitol of the eastern Roman empire. The eastern part of the empire was/is often called the Byzantine. So to make it (hopefully) clear, Byzantium was the capital of the Byzantine empire.

Initially, it was Rome. The capital was moved by Emperor Constantine to Constantople (modern Istanbul) for strategic reasons: it was more easily defended. He named it Nova Roma; it was named after Constantine following his death.
