Structuring the finances

Hi,

I have a LLC and DBA company under it. I will add other companies under the LLC later, but for now it’s one company.
Im going to start off working in the field under the DBA company, but later will step back and oversee everything.
When the DBA company makes money, do I cut a check to the LLC bank account each month? Is there a certain percentage each business should cut to the LLC once I add more? Once I pull my self out the field, do I pay myself from the LLC or the DBA? Should I pay my self an hr wage from the DBA, then a percentage from the LLC?
Should the LLC have a bank account and each company under it have its own?

Please help.

I didn’t find the right solution from the Internet.
