Hi, i have a little problem with textures, and need realize a calc to texturize tiles with precision. Already know what i need in calculations but i could not build the formula. The idea is, have a value example 404 get the third part like 404/3 (the divisor is a variable like the dividend) or A / B. The result of this, must be transformed in a value like X.XX (example 0.32), and the 100 percent is 1.00. That is the idea.

If you want to get texture coordinates out of some large number, you are missing one piece of information: the total number of subdivisions you want. 404 could be 0.79 (404/512 if you use 512 as the largest value) or 0.39 (if you use 404/1024). This is before taking the size of the texture into account, but it might be a good idea to use the size as your divisor, since you aren't gonna get sub-pixel precision.

Come to think of it, you said "tiles", are you referring to this article? If so, you can probably throw my advice out the window since I have no clue about this technique :)
