3942 / 64 / 3 = 3942 / 192. 3942 / 200 is approx 19.7. 3942 / 192 is approx 20.53, which rounds to 21.

Round 3942 to 3900 for easier calculation. Divide 3900 by 64 to get approximately 61, then divide that quotient by 3. The result of 61 divided by 3 is approximately 20.3, making the closest approximate value 21.
