Division of Number

Division

The last of the four operators is division, which literally means splitting thing up. For instance, your father may have given you and your brothers some amount of money to share among yourself. Let say you have three brothers with you, which makes you all four in number. If your father gives you twelve dollars ($12). How will you share it?
$12 ÷ 4 = 3, that means each of you will get $3 each.

TIPS:

• Division has more than one sign, representing it present (fraction slash /, fraction bar    ̶, fraction is related to division).
• When dividing numbers, the first number is called the dividend and the second number is called the divisor, the result is the quotient.
• You can use multiplication table for division; it only cost you to reverse the other of multiplication.

For example, in the multiplication table we learn that 2 × 7 is 14.

So, 14 ÷ 2 = 7, 14 ÷ 7 = 2.

How larger numbers are divides

Example 1.

Dividing larger numbers against one-digit number, dividing 860 ÷ 5.

Unlike other operations, dividing number moves from left to right, so, in this question I will start at the hundreds column.

• First  8 ÷ 5 = 1 (with remainder)
• 1 × 5 = 5 (the 1 from the dividing, multiply by the divisor (5)).
• Write the answer below 8.
• Subtract the 8 and the 5, which equals 3.
• Bring down the 6 to make the number equals 36.
• 5 goes in 36 = 7 (with remainder).
• 7 multiply by 5 = 35.
• Subtract 35 from 36, which equals 1
• Bring down the 0, to make it 10.
• 5 go in 10 = 2.
• 2 × 5 = 10
• Write the 10 below the other 10.
• Subtract the 10 and the 10, which result 0.

We got no more number to bring down, so, finish solving problem.860 ÷ 5 = 172.

Example 2.

Dividing that remains. 77 ÷ 3. Following the above steps.

• There is no number to bring down
• The number that remains below is 2, which is the remainder.

77 ÷ 3 = 25 r 2.

NOTE: When you are dividing number, that the divisor is larger than the dividend. You always get a quotient of 0 with a remainder as the number you started with. For instance,

• 1 ÷ 2 = 0 r 1 (or 0.5 in decimal).
• 3 ÷ 4 = 0 r 3.
