This math topic focuses on division without remainders, using simple one-digit divisors. It revolves around distributing a total number of riders evenly into several cars or buses, then determining the number of riders per vehicle. Each question provides a total count of riders and a specific number of vehicles, and asks how many riders each vehicle would accommodate. This topic serves as an introductory exercise to long division, helping reinforce basic division skills and the concept of evenly splitting quantities.
