Is the word dividir the same in Brazilian and European Portuguese?

Yes

The word "dividir" is identical in both Brazilian and Continental Portuguese in terms of meaning, grammar, spelling, and fundamental usage. The only differences are phonological (pronunciation). In Brazil, the "d" before the "i" is typically palatalized, sounding like the "j" in the English word "jeep." In Portugal, the "d" is dental, pronounced with the tongue against the teeth. Additionally, Brazilian Portuguese tends to have more open, melodic vowels, while Continental Portuguese features more "reduced" or closed vowels.
