This problem can be approached similarly to other base number problems. Since $120<695<720$, divide $695$ by $120$. The quotient is $5$ and the remainder is $95$, so rewrite the number as $$695=5\cdot 120+95$$ Similarly, dividing $95$ by $24$ results in a quotient of $3$ and a remainder of $23$, so the number can be rewritten as $$695=5\cdot 120+3\cdot 24+23$$ Repeat the steps to get $$695=5\cdot 120+3\cdot 24+3\cdot 6+2\cdot 2+1$$ The answer is $\boxed{3}$. One can also stop at the second step by noting $23<24$.
