Question 1041333
{{{(2/5)/(1&3/5)}}}


{{{0.4/(1.60)}}}


Continuing as fractions avoiding use of any long division,
{{{4.0/16}}}


{{{(4)/(4*4)}}}


{{{1/4}}}


You must expect {{{0.25}}}.  You can take the reduced fraction form the division procedure with dividend 1, divisor 4, and perform the process; and you will get  0.25.
