Basically the orthodox view is that Christ wasn’t correct and that the sins of man are reason enough to put asunder what God joined together.
Here is the GOA’s Pastoral Guidelines on Divorce:

And the AOC’s statement on divorce:
“DIVORCE. While extending love and mercy to divorcees, the Orthodox Church is grieved by the tragedy and the pain divorce causes. Though marriage is understood as a sacrament, and thus accomplished by the grace of God and is permanent, the Church does not deal with divorce legalistically, but with compassion. After appropriate pastoral counsel, divorce may be allowed when avenues for reconciliation have been exhausted. If there is a remarriage, the service for a second marriage includes prayers of repentance over the earlier divorce, asking God’s forgiveness and protection for the new union. A third marriage is generally not granted. Clergy who are divorced may be removed, at least for a time, from active ministry, and are not permitted to remarry if they are to remain in the ministry.”
In her pastoral guidelines the Orthodox Church seems to have slightly differing approaches to divorce and remarriage.
I am trying to find a more recent Canon on marriage and remarriage than the Council in Trullo of 697, but am struggling to come up with anything definitive. Here is Canon 87 of Trullo:
“She who has left her husband is an adulteress if she has come to another, according to the
holy and divine Basil, who has gathered this most excellently from the
prophet Jeremiah: If a
woman has become another man’s, her husband shall not return to her, but being defiled she shall remain defiled; and again, He who has an adulteress is senseless and impious. If therefore she appears to have departed from her husband without reason, he is deserving of pardon and she of punishment. And pardon shall be given to him that he may be in communion with the
Church. But he who leaves the wife lawfully given him, and shall take another is guilty of
adultery by the sentence of the Lord. And it has been decreed by our Fathers that they who are such must be weepers for a year, hearers for two years, prostrators for three years, and in the seventh year to stand with the faithful and thus be counted worthy of the Oblation [if with tears they do
penance].”
Side note, although it is claimed that Trullo is the basis of Orthodox canon law, after reading through it I found it difficult to see how it could still be binding on Orthodox Christians, there are so many things that are no longer relevant, or disciplinary actions that make little sense today, not to mention the very dominant Anti-Roman spirit of many of the canons (and this at a time we were in full communion). No wonder it was rejected in the West.
