Quotients of Darboux functions (Q1852373)

There are several papers concerning theorems on a common summand or factors (see, e.g., [\textit{K. Ciesielski} and \textit{A. W. Miller}, Real Anal. Exch. 20, No. 2, 657-672 (1995; Zbl 0830.26004)], or [\textit{T. Natkaniec} and \textit{I. Recław}, Real Anal. Exch. 20, No. 1, 281-285 (1995; Zbl 0833.26005)]). In this paper the author considers analogous problems concerning a common divisor for families of quotients of Darboux functions with respect to the Darboux property.
