I woulld like to use this code:

It is not work:

uint256 vTeamDiv= \_devFee/2; // it is for example 4  
\_rOwned[\_devWalletAddress] = \_rOwned[\_devWalletAddress].add(rDev-(rDev/vTeamDiv)

But this works:  
\_rOwned[\_devWalletAddress] = \_rOwned[\_devWalletAddress].add(rDev-(rDev/4));

what is the problem?

Missing `);` at the end, for one.

What do you mean it doesn't work? What error are you seeing? You need to share more details.

If I divide by uint256 type I can get not good result or zero result, But if I divide normaly number directly it give good result..Why? Need I divide not by uint 256? Wich variable type will good for divide?
