Notes
It is possible to divide by decimals. HOWEVER, it is easier to change divisor to whole number by multiplying both the dividend and the divisor by a factor of 10
e.g. 2.7 ÷ 0.9 ; multiplying both by ten gives you 27 ÷ 9, which is way easier.
Multiplying both the dividend and the divisor by the same factor of 10 does not change the value of the quotient because you are essentially multiplying the entire division problem by 1, which is the multiplicative identity. (This is easier to see if you turn the division problem into a fraction first.)
