=== Division ===
Division is the opposite of multiplication. First position the reticle over the divisor on the D slide. Then without moving the reticule, position the C slide so that the dividend is under the reticule. Read the result off of the D slide under the end of the C slide.
'''Example:''' 2.62 / 1.31 = 2
