Dont worry man, its fine.
I think this means you are using a voltage divider that is not isolated from the mains. Please don't. In real industry it would get you fired because it's an unnecessary risk. The key point is 'unnecessary.'
I am following with interest and I admire your determination to build logic blocks from discrete components. It is, in theory, a good way to understand what goes on inside and I would think it good exercise to build a few gates using different technologies. But to build a reliable multi-stage frequency divider is truly hard work. It was done in the past, yes, but in the days when only a large multinational corporation could afford to own a computer, and they had to hire a full-time technician to keep it functioning.
I have electronic organs from the 1960s that use discrete-transistor frequency dividers. Each stage of division uses about 15 components and needs to be set up for a particular frequency range, like the blocking monostable idea with the 555. |The best of those organs cost as much as a good car, and you got a total of 72 divider stages. At the time it was 'hi-tech' but immediately became obsolete when ICs were designed to do the same job.
So experiment if you wish, but do not beat yourself up if your discrete multistage divider takes too much time or misbehaves at higher frequencies. It was always like that.
