Most people have their own routine and go to the bathroom/toilet the same number of times per day and at around the same time. A person's bowel movement routine is unique to them, and is determined by a number of factors such as diet and what is normal for one person may be abnormal for another. However, stool frequency should be between one and three times a day. If you eat 2 or more times a day you should go at least once a day.
The poo should also be soft and easy to pass but not runny.
The three major ingredients in your feces are water, fibre and microorganisms. If you have plenty of these and still not toileting properly then there may be a physiological reason for low toilet frequency. If your central communication system, your spine, is not in alignment then you may also have some gut problems. I suggest you see and oseotepath or chiropractor. They are not just for back pain. Other critical factors which can have a big impact include the low level of physical activity and or too much stress. Stress can shut down the whole system so do not underestimate the impact it can have on your digestion.
