move the decimal point of the divisor.the times you move the pt. in the divisor the times you will also the pt. in the dividend.
ex:
0.66÷0.22
0.22√0.66 assume that it is a sign for division,,..move the point in in 0.22 two times to the right to become 22 then the dividend 0.66 two times also so it will become 66 then perform the division...so the answer is 3
