The amount of assimilation was not homogeneous anywhere in Europe. In urban environments, some Jewish families were highly assimilated, and there was a great deal of interaction between Jewish people and Gentiles. If these dynamics are interesting to you, you might want to read about the haskalah:
Out in the stetls (in rural towns), there was far less assimilation (although a lot of interaction). For example, in Poland prior to WW2, Jewish society was almost a parallel world. Polish Jews had their own religious institutions, shops, and, at various times, a parallel government. For centuries, Poland was like two separate worlds that inhabited the same physical space.
It's really too bad that it ended. I grieve for something I never even knew.
