How to create subdomain using BIND and domain name server

I want to understand the dns and configuration domain. It is simple to configure using cpanel but I want to configure on server using BIND tool. How to bind subdomain using name server like test.domain.com

ERR_NAME_NOT_RESOLVED

I bought a domain from a hosting firm.

ns1.xxxxx.com  
ns2.xxxxx.com
