When dividing something into two equal parts, one might use the phrase "equally distributed in halves". However, there are other phrases that can also convey the same meaning. One synonym could be "split evenly in two". Another option could be "divided equally down the middle". One could also say that something is "evenly apportioned" or "equitably split". Furthermore, one could use the phrase "equally divided" or simply say that something is "divided 50/50". No matter which phrase is used, the important thing is that the division is fair and equal.
