Scattered sudoku solution

If I were to write the number "2" in the yellow location, then in the 6th column it would not be possible to write the number 2 anywhere. Consequently, the number "2" cannot be R8C5. Therefore, the number "2" is located in the 8th row, in the 8th square (R8C8).

Next, a slightly more complicated trick. So it's worth carefully reviewing why I've written something somewhere. 1. First, I've written some variants in pink in different boxes. "14" is in places where there are 2 empty squares in a row or column or area and the only missing numbers are 1 and 4. (I hope it's understandable). In the middle of the two squares, I've written 2 numbers in pink in places where it is known that these numbers are in these two squares - but it is not known which number is in which. All that is known is that no other number can be there. 2. Then, in darker red, I've marked all the possible numbers that can be written in them in important places. It turns out that the variants in the two areas are in two different columns and have so much in common that there must be at least no. 1 somewhere in both areas. 3. As a result, it can be stated that the gray square shown with green text cannot contain the number "1", because otherwise it is not possible to fill the areas shown with dark red text with numbers "1". 4. In the second picture, the blue arrow shows line no. 6, and this line also shows all the possible places where it is possible to write the number "1". It turns out that there are only 2 possible places for this. 5. No matter which square I write this 1 in, in both cases the number "1" cannot be in square R2C8. Consequently, the number "4" is in this square (shown with yellow).

The following is a sudoku filled with some easy-to-find numbers. I believe there is no need to explain how a number is arrived at. Most of the time it is a matter of filling in the last empty square in a row, column or area.

Next, the "49" is marked in red, where it is known that they are located, but it is not known which one is in which square. Then it is possible to find the numbers in the 9th row. Then in the 1st row and then in the 7th row. The numbers are shown in green.

Then it is known that the missing numbers "2", "4" and "7" are in the grey squares. These can now be neatly placed (shown in red). And then the sudoku is easily solvable.
