Direct vs Regular for Dividend Payout mutual funds


I wish to invest in a dividend payout mutual funds and get around 10lakhs every year as dividend amount.

How much will I need to invest at the start to get 10lakhs of dividend? How should I distribute my portfolio?

Is direct plan better than regular plan even for dividend payout plans? Can you please give an example in numbers? I have read that dividend payout is same for regular and direct or sometimes even more for regular even though the expense ratio is higher for regular. Why so?

What would be the best strategy to get a dividend of 10 lakhs every year?
