WordPress Local Development to Deployment with Version Control

What’s the best practice to implement the Version Control for WordPress Website Development from localhost to Deployment?

Any way better than this?

1. Setup WordPress using MAMP and install your theme and setup everything
2. Push to Bitbucket
3. Push to Live Servver
4. Export the Local DB and Import to Live Server DB

How about future changes? Maintenance after deployment.

1. Export the DB from live server and import to Local DB?
2. Continue the development?
