No, according to the doctrine of the Hypostatic Union, the divine nature did not become fully human, or even partially human.
From the Formula of Chalcedon:
one and the same Christ, Son, Lord, Only-begotten, recognized in two natures, without confusion, without change, without division, without separation; the distinction of natures being in no way annulled by the union, but rather the characteristics of each nature being preserved and coming together to form one person and subsistence
The divine nature is united with the human nature in person of Jesus Christ, but it is unchanged by this union.
Much of the confusion around the HU is placing the two natures in the same category with the person. The person is fully human and fully divine, but the two natures are unchanged.
You ask
What does "without division, without separation" mean?
It means that the two natures can not be separated from each other when discussing the person Jesus. We can not divide the properties of Jesus between the two natures. We all agree that the person Jesus was born of Mary. Under the HU, we can not separate the two natures and say that the man (only) Jesus was born of Mary. We must always say as well that God was born of Mary.
The two natures are united in the person of Jesus but are not changed by the union. The union is so ' stong' that we can not find any separation or division in Jesus.

No, only the Divine Nature (God) is divine.
The human nature (body, soul) of Jesus is not God, Jesus, the Person (the Son, intrinsic to the Divine Nature), to Whom that human nature belongs, is God. Not His human nature: else He would not be human; human natures are not divine. Jesus Christ is truly a "man" (1 Tim 2:5) as well as He is God.

Following, then, the holy Fathers, we all unanimously teach that our Lord Jesus Christ is to us One and the same Son, the Self-same Perfect in Godhead, the Self-same Perfect in Manhood; truly God and truly Man; the Self-same of a rational soul and body; co-essential with the Father according to the Godhead, the Self-same co-essential with us according to the Manhood; like us in all things, sin apart; before the ages begotten of the Father as to the Godhead, but in the last days, the Self-same, for us and for our salvation (born) of Mary the Virgin Theotokos as to the Manhood; One and the Same Christ, Son, Lord, Only-begotten; acknowledged in Two Natures unconfusedly, unchangeably, indivisibly, inseparably; the difference of the Natures being in no way removed because of the Union, but rather the properties of each Nature being preserved, and (both) concurring into One Person and One Hypostasis; not as though He were parted or divided into Two Persons, but One and the Self-same Son and Only-begotten God, Word, Lord, Jesus Christ; even as from the beginning the prophets have taught concerning Him, and as the Lord Jesus Christ Himself hath taught us, and as the Symbol of the Fathers hath handed down to us.
Absolutely not. The divine nature remains forever divine and not human, for that would be a change to the nature and a confusion of the natures.
