Well, for one, you're not dealing with 1 Cor. 7.15, where Paul teaches that if one of the persons in a marriage becomes saved, he or she should not divorce on the basis of that religious commitment, but if the one who did not become a Christian wants a divorce, it's allowed. That has nothing to do with adultery.
Secondly, you're not dealing with Dt. 24.1-4, which is the only law in the OT about divorce, and which doesn't say anything about adultery. We can infer from these verses that divorce is only for good cause, to be handled in a legal setting before a public official, and legal rulings and documents should be provided to protect both of the involved parties for the aftermath. According to these verse, a husband apparently could divorce his wife for personal or for economic reasons.
In Mt. 5.32, this law, like the two others before it, first deals with an action (divorce), and then addresses the motives behind it. While the law can deal with acts (murder, adultery, divorce), no legislation can deal with one's hidden motives. Jesus' statements about anger and lust were never meant to be incorporated into the social and legal code of Israel. What he's talking about is how futile it is to think you can have a relationship with God by your own good works. God is not concerned only that our behavior be in conformity with the letter of the law. Our righteousness must exceed that (Mt. 5.20).
It would also help you to understand the cultural context of Jesus' statement. A few decades before Jesus, some rabbis (following Hillel) had invented a new form of divorce called the "any cause" divorce. By the time of Jesus, this "any cause" divorce had become so popular that almost no one relied on the literal Old Testament grounds for divorce.
The "any cause" divorce was invented from a single word in Dt. 24.1. Moses allowed divorce for "a cause of immorality," There was debate about what "indecent/improper behavior" meant. They debated whether divorce could be for any reason or if there needed to be just cause. But the Hillelite rabbis wondered why Moses had added the word "thing" or "cause" when he only needed to use the word "immorality." They decided this extra word implied another ground for divorce—divorce for "a just cause." They argued that anything, including a burnt meal or wrinkles not there when you married your wife, could be a "just cause"! The text, they said, taught that divorce was allowed both for immorality/improper behavior and for "any cause."
Another group of rabbis (following Shammai) disagreed with this interpretation. They said Moses' words were a single phrase that referred to no type of divorce "except immorality/improper behavior"—and therefore the new "any cause" divorces were invalid. These opposing views were well known to all first-century Jews. And the Pharisees wanted to know where Jesus stood. "Is it lawful to divorce your wife for any cause?" they asked (Matt. 19.3; 5.31). In other words: "Is it lawful for us to use the 'any cause' divorce?"
When Jesus answered with a resounding no, he wasn't condemning "divorce for any cause," but rather the newly invented "any cause" divorce. Jesus agreed firmly with the second group that the phrase didn’t mean divorce was allowable for "immorality" and for "any cause," but that referred to no type of divorce "except immorality." Jesus himself doesn't use the word for adultery in Mt. 5.32, but a much more generic word, πορνείας. While πορνείας is often used of sexual unfaithfulness (though it isn't their word for adultery), it is often used of general unfaithfulness (infidelity) to God. In Rev. 2.14; 9.21, and chapters 17-19, πορνείας is used as a comprehensive term for degeneracy. This is the word Matthew uses to explain what Jesus was saying.
This was a shocking statement for the crowd. It meant they couldn't get a divorce whenever they wanted it—there had to be a lawful cause. It also meant that virtually every divorced man or women was not really divorced, because most of them had "any cause" divorces. Luke and Matthew summarized the whole debate in one sentence: Any divorced person who remarried was committing adultery (Mt. 5.32; Lk. 16.18), because they were still married. The fact that they said "any divorced person" instead of "virtually all divorced people" is typical Jewish hyperbole—like Mark saying that "everyone" in Jerusalem came to be baptized by John (Mk. 1.5). It may not be obvious to us, but their first readers understood clearly what they meant.
