How can i split the expenses in two different types like fixed and variable expenses?

Since there is nothing called a fixed or predictable budget, you need to plan your expenses every month. Life changes, time changes, situations change, and so should your budget. I can tell from experience that being as predictable as possible will help you have more fixed expenses and less variable ones. For instance, the mortgage or rent you pay every month, the salary you pay to your security guard, the monthly installments for a certain loan you took, insurance, and electricity and water bill form a part of your fixed expenses. 

Whereas, unpredictable or unforeseen expenses, such as the check you received for an expensive dinner from last night, the shopping trip with your friends, the expensive phone plan form a part of your variable expenses. There can be other types of variable expenses as well, such as your car may break down all of a sudden, you may need to get immediate repairs at home or office, you might need to buy a new phone, etc. 

What you can do to have a month with more planned or fixed expenses is that you can try to plan most parts of your expenses. Knowing which, you will be able to identify and cut down on unnecessary expenditure. For example, you can move down to a cheaper wifi/phone plan and create a list of things you actually need to buy. Also, conduct an occasional check of your past months' spending history. Your bank statement and credit card expenses can be a real help in this.
