No biggie, to use the technical term. It takes a hundred cents to make a buck, so the cents place is the hundredths, which is currently occupied by the 6.
When rounding, you are merely borrowing backward, asking the number to the right if it is able to pretend it is ten, or if it is too small and acts like 0 instead. If you ever draw a blank during a test, just hold up both of your hands and start counting from zero. On the left hand, you will count, {0,1,2,3,4} and on the right, {5,6,7,8,9}. If the number to the right is on your left hand, don't round up. If on your right, do round up.
In your case, the 7 is on your right hand, so up! The 6 becomes a 7, and you get:
0.87
