Although there are few differences, it is important to highlight that there are basically two types of audits: Internal or Independent.
Internal auditing is an independent and objective assessment and consultancy activity, created to add value and improve an organization's operations. It helps the organization achieve its objectives by applying a systematic and disciplined approach to evaluating and improving the effectiveness of risk management, control and governance processes.
This is a definition commonly used by the Institute of Internal Auditors (The IIA Global) to define audit activity.
IIA Global issues Standards for carrying out internal audit work that are currently under review.
I suggest you take a look at The IIA Global website (https://www.theiia.org) and search for the new Standards. There you can find in detail all the steps for carrying out an audit.
Another option is to look on standards websites (ISO), for example, to check standards for carrying out audits.
