It seems there was an error with the text encoding in the word "założenie." If that's the word you mean, its English definition is "assumption" or "establishment," depending on context.
Here, 'założyłem' is used to mean 'I opened or established,' referring to setting up something, such as a bank account.
Założyłem nowe konto w banku.
I opened a new account at the bank.
In this sentence, 'zakładając' (a form of 'założyć') is used to describe the act of putting on clothing.
Zakładając ciepły płaszcz, ochronisz się przed zimnem.
By putting on a warm coat, you will protect yourself from the cold.
Here, 'zakładam' means 'I assume or presume,' indicating a supposition or hypothesis.
