How did the Varna System(Caste System) helped in spread buddhism in India?

The Caste System of India. Caste not only dictates one's occupation, but dietary habits and interaction with members of other castes as well. Members of a high caste enjoy more wealth and opportunities while members of a low caste perform menial jobs. Outside of the caste system are the Untouchables.

Buddha denounced the caste system and taught that a person's actions are the measure of who a person is, whether a priest or outcast. He denounced the authority of Brahmin priests, their scripture and their rituals. ... It is not an easy system to abolish, even with the force of law. Buddhism and Hinduism agree on karma, dharma, moksha and reincarnation. They are different in that Buddhism rejects the priests of Hinduism, the formal rituals, and the caste system.
