How to do them fast
Split the number into a part the divisor goes into tens of times, and the rest.
156 ÷ 6 = 26
156 = 120 + 36 → 120 ÷ 6 = 20 → 36 ÷ 6 = 6 → 26
Dividing by 4 or 8 is halving two or three times.
184 ÷ 8 = 23
184 → 92 → 46 → 23 (halve three times)
Around 4 seconds each is good; under 3 is fast. More methods are in the mental math tricks.
