There are divisions among those who adhere to false religions also. Division is inherent in humans in the natural.
Being non-denominational can also bring problems, for there are many non-denominational churches that take on that assignation, but they can be just as off the wall as some denominations---cultish, even.
Why recommend a denominational church to anyone, if you think poorly of them? I grew up in an excellent denominational church---the Christian and Missionary Alliance. If I would recommend any church, I would recommend that, or The Vineyard.
However, if one seriously wants to find the church family God is calling him to, then merely stop and pray about it and ask God to lead. He has a people in mind for everyone, and the problem is that many do not seek His leading, but go to where they feel good. It isn't about feelings. A great church is one who preaches the truth of the word, even on matters that aren't popular, and one that challenges you to live out your faith, and to come up higher in the Lord, to seek more and more of God. A church that teaches us to see a need and fill it is an outward-focused church and a gem! If that is a non-denominational church, then get there in a hurry!
