I guess that by Constantine you mean Constantine the Great. Constantine and Ambrose were not really contemporaries. Ambrose was only 7 when Constantine died. He was not involved in decisions regarding the empire.
Ambrose is better known as St Ambrose. He was the bishop of Milan and one of the Latin doctors of the Church, or 'fathers' of the Catholic Church. His theology contributed to laying the foundation of the Catholic doctrine. In payed an important part in shaping the doctrine of the immaculate conception. He saw virginity as superior to marriage and Mary as a model for this. His writings on ethics were also important. He also opposed the Arianism of emperor Velentinian II.
Constantine didn't split the Roman Empire. It was Diocletian, and he divided the empire into western and eastern halves.
The two emperors who tried to restore order in the Roman Empire were Diocletian and Constantine I (or the Great).
Constantine split the Roman Empire into the Holy Roman Empire and the Byzantine Empire. It should be noted however that the emperor Diocletian (284-305 AD ) made this easier as he was the first to divide the empire into two parts, a western and eastern empire to be ruled separately. The emperors who followed Constantine, Julian and Theodosius I, made permanent the division of the Roman Empire into an eastern and western half.
The Emperor Constantine the Great (also known as Constantine I) moved the capital of the old Roman Empire to the Ancient Greek city in the East called Byzantium, and renamed this city as "Constantinople - the New Rome" in the year 330 AD. Constantinople remained the capital of the New Roman (or Eastern Roman) Empire until the year 1453 AD.

Constantine didn't split the Roman Empire. It was Diocletian, and he divided the empire into western and eastern halves.
Emperor Constantine reunited the Roman Empire in 324 AD after it had been split by Emperor Diocletian. But soon after his death the empire would again be divided. The east would survive; the west would fall
Constantine made Christianity a legal religion in the Roman Empire. He also moved the capitol of the Roman Empire from Rome to Constantinople (modern day Istanbul).
Constantine ruled over the Roman Empire from 306 to 337 AD
In the Roman Empire up to the time of Constantine, the official religion was Greco-Roman paganism. After Constantine it became Christianity.
The Roman Emperor Constantine I the Great divided the Roman Empire to the west Roman Empire and the east Roman Empire and moved his capital city from Rome to the ancient Greek city of Byzantium which was renamed as New Rome. After Constantine's death his successors renamed the city as Constantinople, a name that survived its conquest by the Ottomans, until 1923 AD.

No, Constantine died over 100 years before the West Roman Empire fell, and over 1100 years before the East Roman Empire (Byzantine Empire) fell.
Constantine gained complete control of the Roman empire in either 314 or 316. Sources differ on the year.
Constantine the Great designated Byzantium as his imperial capital, redeveloped and renamed it Constantinople, after himself - Constantinople means city of Constantine. However, this did not lead to the beginning of the Byzantine Empire. In fact, the Byzantine Empire did not actually exist. This is a term which has been coined by historians to indicate the eastern part of the Roman Empire after the fall of the western part of this empire and which became popular in the 19th century. The people in question did not know this term and called their empire Roman Empire. Therefore, it would be more appropriate to talk of a "Byzantine" period. This started about a century later.
