Topics are further subdivided into partitions. A record is published to exactly one partition in a topic, and it's guarenteed exactly one consumer in a given consumer group will read from a given partition at a given point in time.

See, for a rundown on how mismatches between the number of consumers (in a group) and the number of topic partitions are handled by Kafka.
