I haven't gotten to 100 million installs, but I have a few Play apps and one got to 7 million installs. This post is most right on that I've seen here. Back in 2011-2012 you could have a hit without generating your own installs to it. With more competition nowadays, that happening would be much rarer.

You need to generate your own installs at first. Google will look at your uninstall ratio, and perhaps other factors. If those factors are good, Google will start pushing you up the keyword and then category rankings in various countries. Then people will start ranking your app, and that will factor in. Google has made some public announcements about what they take into account, and there are many outside accounts out there with guesses, some good, some not, at what helps.

Making an app people want helps. Having a clear, simple icon and clear app name helps. If the app does offline maps, call it Offline Maps. If several reviews and e-mails suggest adding a feature, consider adding the feature. And so on.

I have not found cross-promotion helpful In the mannernthe article says. If you run ads, and get one cent for every ten ads shown on average, then you're losing a cent every ten times you show your ad. It might be cheaper to advertise it in other venues. In some circumstances cross-promotion makes sense. You can set a minimum bid for your ad network, and show your ads when the ad network can't make that bid. Also, for new apps, I often put the first ad in as a cross-promotion ad. I see how the app does, and how much it refers. If all is well and the app is taking off and doing referrals, I put an ad network ad in the app.
