Long division calculator

Hi, I'm a long division calculator. I will become your assistant in everyday tasks, such as solving homework. After all, I can produce multiplication, addition, subtraction and division by a column of any numbers in an instant! The task can be entered using the comfortable keyboard, which can be easily hidden for the convenience of viewing the solution. The solution field can be easily scrolled, zoomed in and out, because it stores up to 100 calculations! Any operation supports the input of fractional numbers, and division can determine the frequency of the resulting fractional number, it can also divide the number with a remainder or with an accuracy of 100 decimal places! My options include:
• Long division with a certain accuracy, as well as with the remainder, and determining the period of the fraction
