In this exercise, we will look at the long-division method. The long-division method is used when we wish to divide a big number, say 2145 by a smaller number, say 5.
Note, you should have mastered the multiplication tables before you attempt this exercise.
The long-division method is done in several steps:
Let us see the long-division method in an example. Let us say we want to divide 81 candies into 3 friends. We would write the problem as:
Now, since the first digit of the divident (81) is smaller than the divisor (3), we would calculate 8 ÷ 3. Think of this as if you had 8 candies and you want to divide them amongst 3 friends. So, each friend would get 2 candies. This is the first step:
|Step 1.Find the largest number that will divide the first digit of the divident.|
|Step 2. Next, we multiply the quotient from the previous step with the divisor and write it like this.|
|Step 3. Subtract|
|Step 4. Bring next digit of the dividend down|
|Step 5. Repeat all the steps above until you cant divide any more. If we combine all the steps into one step, we have:|
|Step 6. So, the final answer is 27|
So, the final answer of 81 ÷ 3 is 27.
