1, write 22÷3 in the format of vertical calculation.

2. From the highest place: the tenth place: 2 ÷ 3 = 0.2, because it is the highest place, so there is no need to write the number 0. The remainder 2 is incorporated into the calculation of bits.

3. Unit: 22 ÷ 3 = 7. 1, that is, the number of units is 7, and the remainder is 1, which is not divisible.

Namely: 22 ÷ 3 = 7. 1.
