When you'd hear it
This is common in spoken Korean, from casual conversation to polite explanations at work or in class. It also appears in written interviews and personal writing, especially when explaining how a situation led to a result or realization.
What learners get wrong
Learners often confuse this with -다가, which describes one action changing or being interrupted by another. In -다(가) 보니(까), the whole pattern presents an ongoing situation and its resulting discovery or consequence; the 가 is optional.
