By definition, a rational number is a number that can be expressed as the quotient of two integers. This quotient is called fraction and is written as $\frac{a}{b}$. Hence, division and fraction are the same, at least in the context of dividing integers and turning them into rationals. This concept is expanded in middle school for dividing irrationals and polynomials.

Everyone whom I know uses division and fractions interchangeably depending on whichever is simpler in a particular case, but fractional form is the preferred one. I do the same, in fact, this is how I was taught in school.

Say, $5 \div 3 \times 6 \div 2 \div 10 + \frac{3}{8}$ turns into $\frac{5 \times 6}{3 \times 2 \times 10} + \frac{3}{8} = \frac{1}{2} + \frac{3}{8} = \frac{4 + 3}{8} = \frac{7}{8} $
