because that's how many times the quotient goes into the whole number.
100 divided by 4 = 25
100 divided by a lesser number than 4, say 2, = 50
100 divided by an even lesser number than 4, say 1, = 100.
Notice the pattern. Each time we divide by a lesser number, the quotient (the answer) gets larger and larger
Dividing by 1 already equals a quotient that is EQUAL to the original number we are dividing.
Thus, for the pattern to continue, the quotient must become greater than the number.
100 divided by an even lesser number than 1, say .5 = 200.
