It is not comfortable to divide BY a decimal, so we multiply by powers of #10# to change what the question looks like.

#0.89 div 5.60 = 0.89/5.6#

#0.89/5.6 xx10/10 = 8.9/56" "rarr (10/10 = 1)#so the value stays the same.

Now you can divide as usual because the denominator is a whole number, not a decimal fraction.

#color(white)(........x.........)ul(0.1589)#

#color(white)(..............)56)8.9000#

#color(white)(....................)ul56#

#color(white)(....................)330#

#color(white)(....................)ul280#

#color(white)(.......................)500#

#color(white)(.......................)ul448#

#color(white)(..........................)520#

#color(white)(..........................)ul504#

The answer is a recurring decimal. From this answer we can round off to 3 decimal places to get #0.159#
