0.57/-0.19 = 57/-19 = -3

Notice how you can move the decimal point wherever you want so long as you move it the same number of places in both the numerator and denominator. Also note that what I did was to multiply both numerator and denominator by 100.

If your calculator is giving -0.03, then you are not entering the correct inputs.


For doing "long division" on paper, do you understand fractions and decimals?
%280.57%2F%28-0.19%29%29%28100%2F100%29=-57%2F19, which is now 57 divided by negative 19.
