If I understand your question correctly, the answer is that the meeting that divided Africa took place in Berlin, Germany. This meeting was held in 1884 and 1885. It is typically known as the Berlin Conference of 1884-5.
The point of the Berlin Conference was to organize the European countries’ exploitation of Africa. Before the conference, the various European countries were engaged in what is commonly known as the “Scramble for Africa.” Each country was trying to get as much territory as it could. Eventually, this started to worry European leaders. They felt that the competition for territory was likely to lead to more open conflict between their countries. Therefore, they thought that it would be a good idea to have a meeting at which they could agree on which country would get what part of Africa. This was the purpose of the Berlin Conference. At the conference, major European leaders divided up Africa, agreed to allow free trade between colonies on the continent, and set up procedures for dealing with disputes. Therefore, the best answer to your question is most likely Berlin.
