$\sf \\\\ \Rightarrow \ \ \ 33 \ \div \ \{ \ 10 \ + \ [ \ 6 \ \div \ 3 \ + \ ( \ 1 \ + \ 2 \ )] \ - \ 4 \ \} \\\\ \Rightarrow \ \ \ 33 \ \div \ \{ \ 10 \ + \ [ \ 2 \ + \ 3 \ ] \ - \ 4 \ \} \\\\ \Rightarrow \ \ \ 33 \ \div \ \{ \ 10 \ + \ 5 \ - \ 4 \ \} \\\\ \Rightarrow \ \ \ 33 \ \div \ 11 \\\\ \Rightarrow \ \ \ \boxed{ \ 3 \ }$
