Dividing by decimal numbers seems difficult at first because no one has taught you the “0, 7 times table”. The secret to doing this is to convert the division problem to a format that only uses whole numbers. After you rewrite the problem in this way, it will become a regular long division problem.

A parallel line is two lines in a plane that will never meet (meaning that the two lines will not intersect each other even if they are extended indefinitely). The key feature of parallel lines is that they have exactly the same slope. The slope of a line is defined as the vertical increase (change in the Y coordinate) to the horizontal increase (change in the coordinates of the X axis) of a line, in other words, the slope is the slope of a line.
