I hear this term a lot, “Biblical divorce.”

Most commonly it means having the fault ground of Adultery as the basis for the divorce. It is widely held that this is the only “Biblical Ground” for divorce and absent Adultery you cannot or should not get a divorce.
“Biblical grounds” can also include abuse and abandonment, depending upon your denomination. These, adding to the list the reasons that a divorce may be allowed.
Interestingly, the Bible also states “I say to you that everyone who looks at a another with lust has already committed adultery in his heart.” Mt. 5:28 This expresses the idea that lust for another, not your spouse, is “Biblical Grounds” for divorce.
Divorce is something no one really plans for (prenups notwithstanding). It is something that is routinely despised yet, it is also sometimes very necessary.

The concept of “Biblical” grounds for divorce are not universally recognized, it should be noted, and in the Western world are uniformly post Reformation. Prior to the Reformation, in the west, no grounds for divorce were recognized, in keeping with Christ’s statements that whoever put his wife aside and took another committed adultery. Annulment was recognized, but that’s actually quite a different concept. In the East, divorce came to be tolerated to an extent, although I don’t know when, in recognition of human frailty but the status of the divorced and remarried, in so far as I understand it, isn’t really clearly spelled out.
Even in the early Reformation divorce was not recognized, and at least some of the early Protestant churches rejected its validity. It really came in after that as a civil institution, and in spite of what current concepts of it may in these regards, it established itself as a civil institution and that was slowly tolerated in various Protestant denominations at a much later date.
This, of course, is from a Christian prospective. In the Jewish faith it was possible to obtain a “get”, which is a divorce that was essentially approved by a Rabbi under prescribed conditions.
