Is there a such thing as an easy divorce?

Ok I know a lof of people that got divorced (including me) but dont know hardly anyone that had a smooth divorce but one person! Why is this? If two people decide to divorce why all the fighting, cussing, insults, and etc have to happen? Divorce lawyers love it when the two go back n forth to court because their bill goes higher! Can’t we just agree to disagree! Why fight and bicker if we’ve agreed the marriage just aint workin out? Talk to me!
