Hiki mawashi (two handed pull around) is a foundational movement. Often why this natural movement is tricky for us humans is we tend to use our limbs independently of our body. This simple video shows a minor but important detail about that.
The take down demonstrated is uchimomo Geri (inside thigh kick). Two important details:
1) angle of entry is analogous to attacking a tripod; an odd Enshin hobby, but from the inside out.
2) the back swing upon dismantling is just as important to lead their center of mass in a non competing direction. Avoid the surfer off into the sunset movement.
