Dividing, like subtracting takes a bit more work.

• Dividing by zero.
  Dividing a number by zero is always zero. An exaggerated example often helps to illustrate the point: a trillion divided by zero is zero.
• Dividing by one.
  A number divided by one is the number. Again use exaggeration: One zillion divided by one is a zillion.
• Dividing by two.
  Divided by two is a half of the number. eg. 4 ÷ 2 = 2
• Dividing by four.
  Cut the number in half twice. eg. 32 ÷ 4 = (32 ÷ 2 = 16) and (16 ÷ 2 = 8)
• Dividing by five.
  Count by fives until you reach the number. This is another time when an older student is allowed to use their fingers. eg. 45 ÷ 5 = nine fingers
• Dividing by nine.
  Lay your hands on the desk, fold under a finger using the multiplying by nine method to create the number being divided. The folded finger is your answer. eg. 63÷9. The folded finger is 7.
• Dividing by eight.
  Cut the number in half three times. eg. 64 ÷ 8 = (64 ÷ 2 = 32) and (32 ÷ 2 = 16) and (16 ÷ 2 = 8)
• Dividing by three, six and seven.
  Look at this as upside down multiplying. What times three equals twenty-one.
  eg. 21 ÷ 3 = 3 x ? = 21 .
