in dividing decimals you never get a remainder and in dividing whole numbers you do. +++ More to the point perhaps, you are working in powers of 10 all the time.
In all of these cases the result is positive.
In that you carry out exactly the same steps - AND you must determine the correct position of the decimal point.
Consider 23/1.344 This can be written as 23000/1344 (we multiplied both numerator and denominator by 1000 and doing so does not change the original value). Lo and behold we have converted dividing by decimal to dividing whole numbers. Consider 23.089/4.6788 This can be written as 230890/46788 (we multiplied both numerator and denominator by 10000 and doing so does not change the original value). Lo and behold we have converted dividing by decimal to dividing whole numbers.
The rules for dividing negative numbers is the same as multiplying them. A negative number multiplied/divided by a negative number is positive and a negative number multiplied/divided by a positive number is negative.
