Answer:

#79div4.5=color(blue)(17.555bar5)#

Explanation:

While this can be done directly, it is probably easier to first multiply both the dividend and the division by #2# to avoid the fractional component.

#79 div 4.5#
#color(white)("XXX")=(79xx2) div (4.5xx2)#

#color(white)("XXX")=158 div 9#

(then either by inspection or long division)
#color(white)("XXX")=17 5/9#

...or as a repeating decimal
#color(white)("XXX")=17.55bar5#
