The Order of Operations is incorrect for division. That's because 5th grade math teaches that division is a fraction (and vice versa). Also, in teaching how to divide by a monomial in 9th grade Basic Algebra, it is consistently shown as a top-and-bottom fraction. Here are some of the many examples of how these concepts are currently being taught to young math students:
"Anyone who has studied secondary school mathematics would probably be comfortable with the convention of 'a over b' meaning 'a divided by b'."

"What are the tips and rules for simplify algebraic expressions?"
"An individual needs to know the rules of simplifying algebraic expressions before solving them. Some basic rules are combined to facilitate the given algebraic expression.
"...Open the brackets in the expression by using the distributive law."
"The distributive property, in particular, asserts that given any absolute values a, b, and c, one should simplify the components of the parenthesis first.
When the elements of brackets are difficult to be simplified, use the distributive property to multiply each term within the parenthesis by the factor outside the parentheses. One can multiply and delete the parenthesis by using the distributive property."

"In Algebra, a polynomial with a single term is known as a monomial. When a monomial is divided by a monomial, first divide the coefficients of the variable and then divide the variable when the variables are present in both the numerator and denominator. For example, assume two monomials, 50 xy and 5y. Now the monomial 50xy is divided by 5y, we will get
= 50xy/5y
= 10x
Thus, the quotient value obtained is 10x, which is the result of the division process."

"A monomial is a form of a polynomial with a single non-zero term. Because a monomial has only a single term, it is simple to do addition, subtraction, and multiplication. It is composed of only one variable, one coefficient, or the product of a variable and a coefficient, with exponents as whole numbers representing only one term."
"...when dividing monomials, divide the coefficients first, then divide the variables. When there are exponents with the same base, divide by subtracting the exponents according to exponent rules.
Example: 16mn ÷ 4n
= (16/4) (m) (n/n)
= 4mn "
