In modern usage, do-support requires that the form do not ... (or don’t ...) be preferred to ... not for all but a short list of verbs (be, have, can, shall, will, would, may, must, need, ought):
They do not sow. (modern) vs. They sow not. (KJB)
American usage tends to prefer don’t have or haven’t got to have not or haven’t, except when have is used as an auxiliary (or in the idiom have-not):
I don’t have a clue or I haven’t got a clue. (US)
I haven’t a clue or I haven’t got a clue. (outside US)
I haven’t been to Spain. (universal)
The verb need is only directly negated when used as an auxiliary, and even this usage is rare, especially in the US.
You don’t need to trouble yourself. (common)
You needn’t trouble yourself. (outside US, rare)
I don’t need any eggs today. (universal)
The verb dare can sometimes be directly negated.

The verb do, as a main verb, takes do not.
He does not do that.
In the imperative, all verbs, including be, take do not.
Don't do that.
Don't be silly. (not *Be not silly.)
In the infinitive, verbs must be negated directly. In this case not cannot appear after the verb; some authorities recommend placing it before to to avoid a split infinitive, but for most speakers the forms not to do and to not do are more or less interchangeable, with the latter being mostly informal.
The objective is not to lose or The objective is to not lose.
I wanted not to go or I wanted to not go. (Note the difference between this and I didn't want to go, where want is the verb being negated.)
In the subjunctive mood, do-support is not used for negation; not is placed by itself, or with should, immediately before the verb it modifies, even be:
They suggested that he (should) not do it.
The law requires that it (should) not be done.
not to put too fine a point on it
