The document discusses patterns in division and provides examples to illustrate definitions and concepts related to division. It defines dividend, divisor, and quotient, and shows that the dividend goes inside the division bracket, the divisor goes outside, and the quotient goes above. Examples are provided to demonstrate that for larger numbers, the same patterns can be used, such as 160 divided by 8 being 20 since 16 divided by 8 is 2. Patterns are also shown for numbers with zeros, such as 32,000 divided by 8 being 4,000.
