Currently, i am finding a way to perform the casting operation by the default cast screen button given in the drop down menu for android 4.4 above(most probably). But there is another way using software and apps available in the Google Play Store.

All Cast Receiver Vysor

In both of these cases its as simple as installing the android app on your android device and adding the extension for the corresponding app installed and then just launch the extension and connect to the available network available from your android device. Note-> Both These extensions are for Chrome.

If you are still having problems with getting started just Google the application names and you would find someone making money with your required video on youtube.
