How can I wash dishes and keep dairy, meat and pareve separate if I have one sink in my kitchen?🚰🧽

I do if I only have one kitchen sink so contrary to what some people think you could have a kosher kitchen with one sink in fact years ago probably most people most families had only one sink in their kitchen it's a luxury if you can to have separate sinks but it's not necessary what should you do well best is to have separate tubs you put your meat tub and you wash your meat dishes you have your Dairy tub and you wash your Dairy dishes if you're going to take out the tubs then the the rest of the sink we view the sink as being not kosher and therefore you could dump whatever you would into your sink but when you're washing your dishes you use the tub some people use a rack on the bottom of their sink and either way is fine
