5 goes 16 times into 82, because 16 * 5 = 80, and you have a remainder of 2. So
- 82/5
= - [ 80/5 + 2/5 ]
= - [ 16 2/5 ]
= - [ 16 + 2/5 ]
Now, multiply both numerator and denominator of that proper fraction by 20, so you get a new fraction whose denominator is a power of ten (100 in this case):
You can just multiply the top and the bottom by 2, to get the bottom to be 10. So you get -164/10. From here you can see that 10 goes into 164,16.4 times.
