Company X has 1 share for $100 and Company Y has 1 share for $10.
If I have $100, should I buy 1 share from Company X or 10 share from Company Y provided that both companies are equal in every aspect & both have same dividend yield ?

@cool like a bird,
when you look at both the companies they both have same yield, but company X looks more stable than company Y. Since company Y is cheaper, it's price can be easily manipulated, I believe. And you know, the yield changes with price of the stock. If you need a steady income through dividend, you should choose a stable company.
Utilities companies are pretty strong financially and can be good source of income for conservative investors. Similarly, gas and oil companies are also very profitable. But these days due to low crude oil price American companies are cutting dividends. They can no longer pay dividends. We don't know what's gonna happen next. You should look at $LINE. Look how this company has disappointed so many conservative investors.
What I would recommend is: do your due diligence and buy the stock. You may want to buy company Y if it is undervalued.

Which stocks do you have in your portfolio for long term dividend investing ?

To tell you the truth I don't have any stock in my portfolio that pays dividend. I'm an aggressive investor/trader. I will be more conservative as I grow older.
