I did not do did you do? didnt you do?
等do可以用在进行式或一般式中:

Whats he doing tomorrow?
他明天要做什么?(最近将来)
What does he do in the evening?

How do you do?是经过介绍之后双方互致的问候语:
Hostess:Mr Day,may I introduce Mr Davis?Mr Davis, Mr Day.
女主人:戴先生,让我来介绍戴维斯先生。这位是戴维斯先生,这位是戴先生。
两位先生这时都说:
How do you do?
您好。
原先这是问候对方健康的话,现在仅用为介绍场合中的公式化的问候语。
do的其他用法如:
He doesnt do what hes told.
他不按照告诉他的去做。(不服从命令)
What do you do for a living?
Im an artist.

to do with(只限于动词不定式)有有关系的意思。主要用于 it is/was something/nothing to do with+名词/代词/动名词结构:
Its nothing to do with you.相当于:
It doesnt concern you.
这跟你没关系。
