**SINGLE-DIGIT DIVISION**is having one digit as a divisor and multiple digits as the dividend. Watch the video to understand single-digit division.

**DOUBLE-DIGIT DIVISION**is having two digits as the divisor and multiple digits as the dividend. Watch the video to understand double-digit division.

**RULES OF DIVISIBILITY**- There are cool tricks to help decide what a number can be divided by without having a remainder. These rules also help to determine if a number is PRIME (only has two factors) or COMPOSITE (has more than two factors). Here are the rules:

**Divisible by**

**2**- If the dividend ends with an even number or zero, you can divide it by two.

**Divisible by**

**3**- Add the digits in the dividend. If the sum is divisible by three, then the whole dividend is divisible by three.

**Divisible**by

**4**- If the last two digits of the dividend are divisible by 4, then the whole dividend is divisible by 4.

**Divisible**by

**5**- If the dividend ends in zero or five, you can divide by five.

**Divisible**by

**6**- If the dividend can be divided by both two and three, you can also divide it by six.

**Divisible**by

**7**- Double the last digit of the dividend, then subtract that from the first several digits of the dividend (not including the last digit). If the answer is 0 or divisible by 7, then the dividend can be divided by seven. (dividend=672 double the 2 equals 4. Subtract 4 from 67 to get 63. 63 is divisible by seven, so the whole dividend is divisible by seven.)

**Divisible**by

**8**- If the last three digits of the dividend are divisible by eight, then the whole dividend is divisible by eight.

Divisible by

**9**- If the sum of the dividend's digits is divisible by nine, then the whole dividend is divisible by 9.

**Divisible**by

**10**- If the dividend ends in a zero, then you can divide by 10.

**Divisible**by

**12**- If the dividend is divisible by both three and four, it is divisible by 12.
