what is the different between "do with" and "deal with"

do with 常与连接代词 what 连用,而 deal with 常与连接副词 how 连用,如：
1 .I don’t know how they deal with the problem .(= I don‘t know what they do with the problem .)我不知道他们如何处理这个问题.
2 .He is easy to deal with .(= He is easy to do with .这时“do”是不及物动词)他是容易相处的人.这两个词组在使用时有细微的差别.一般地说,do with 表示“处置”、“忍受”、“相处”、“有关”等.如：

3 .We are difficult to do with the new comer .我们很难与新来的那个人相处.
