Who knows what procedure the question is referring to... You can take advantage of the distributive property of multiplication to compute the product:
715 * 211 = 715 * (200 + 10 + 1) = 715 * 200 + 715 * 10 + 715 * 1
Computing the remaining products is trivial.
715 * 200 = 2 * 715 * 100 = 1430 * 100 = 143,000
715 * 10 = 7150
715 * 1 = 715
Then
715 * 211 = 143,000 + 7150 + 715 = 150,865
