How do I withdraw my Solana?

Excuse me, I'm having some trouble with withdrawing my Solana from my digital wallet. Could you please guide me through the process step-by-step? I'm a bit new to this and would appreciate any clarity on the necessary precautions I should take, as well as any fees that may be associated with the withdrawal. Additionally, could you clarify the time it typically takes for the Solana to be transferred to my designated account? Thank you in advance for your assistance.
