00:00What is division? Division is breaking up of number in equal
00:10number of parts. It can also be said division is repeated subtraction.
00:20The division is represented as shown. Division is represented by this equation.
00:30Dividend divided by divisor is equal to quotient. It is also represented as shown.
00:44What is Dividend? Dividend is the number which we are dividing.
00:50What is divisor? The divisor is the number which we are dividing
00:55by. And the quotient is the result or the answer.
01:03Let's take an example of dividing 28 by 2. When we divide 28 by 2, the result we get
01:12is 14. Here 28 is dividend, 2 is divisor and 14 is quotient.
01:27The steps of division. Division is done in 4 steps.
01:36To memorize it, we call it DADDY, MUMMY, SISTER, BROTHER.
01:42The first step is DADDY, that is to divide. Second step is MUMMY, that is to multiply.
01:51The third step is SISTER, that is to subtract. And the fourth step is BROTHER, that is to
02:00We repeat these steps till we get the result. Let's look at the division of 2 digit number
02:13by 1 digit number. We will divide 28 by 2. It can be written
02:25as shown. We will first look at the table of 2.
02:302 multiplied by 1 is 2. 2 multiplied by 2 is 4.
02:412 multiplied by 3 is 6. 2 multiplied by 4 is 8.
02:502 multiplied by 5 is 10. Coming back to the example, we will start
03:00the process from the leftmost digit. First we will divide.
03:062 divided by 2 is 1. 1 will be written in the quotient.
03:16Then the step is to multiply. Divide is multiplied by quotient.
03:222 multiplied by 1 is 2, which is written down as shown.
03:30Then the third step is to subtract. We subtract 2 minus 2 and we get a result
03:36of 0. The fourth step is to bring down.
03:444 will be written in the quotient. Then quotient multiplied by divisor is 8, which
04:02is written as shown. The next step is to subtract.
04:058 minus 8 is 0. Therefore, when we divide 28 by 2, we get
04:1614 as a result.
