Imagine for a moment we have some leftover pie, amounting to 5/12 of a pie and we want to find how many 1/8-sized pieces can be cut from the leftovers. We could calculate this amount by dividing 5/12 by 1/8.
5/12 ÷ 1/8 = 5/12 × 8/1 = 40/12 = 3 1/3
To divide a number by a fraction, we multiply the number by the reciprocal of the fraction:

Division of signed fractions
Just as for all operations, the same basic methods apply to signed fractions. The only extra complication is that we must remember to deal with the sign. Decide the sign first before you divide so you don't forget.
