How do we estimate $10^{23}$ stars in the observable universe?

Now, I read somewhere, that there are 4,106,234 stars in the observable universe. How did scientists estimate this?

The figure of 4,106,234 stars is not correct. A single galaxy contains an average of about 100 to 200 billion stars, and there are many thousands of galaxies.
