## Decimal to binary

`int data_holder = 33;`

As shown in the above statement, when we assign a decimal value to a variable, first the value is converted to binary from decimal value, and later it will be stored in computer memory space. Let’s see how to do that.

Consider the decimal value is ** 33**. Now to get the binary value from this decimal value divide this value with ‘2’ repeatedly until you get ‘1’.

`100001`

After dividing it, note down the remainder from bottom to top. Then the binary value looks like

At each step, note down the remainder that you are getting. For more info see the below picture.
