The actual process of borrowing is complex and involves many usage events (i.e. instances of use of the new word). Generally, some speakers of the borrowing language know the source language too, or at least enough of it to utilize the relevant word. They (often consciously) adopt the new word when speaking the borrowing language, because it most exactly fits the idea they are trying to express. If they are bilingual in the source language, which is often the case, they might pronounce the words the same or similar to the way they are pronounced in the source language. For example, English speakers adopted the word garage from French, at first with a pronunciation nearer to the French pronunciation than is now usually found. Presumably the very first speakers who used the word in English knew at least some French and heard the word used by French speakers, in a French-speaking context.
