what's 4 divided by 523

$$\frac{4}{523}$$

or

$${\frac{{\mathtt{4}}}{{\mathtt{523}}}} = {\mathtt{0.007\: \!648\: \!183\: \!556\: \!405\: \!4}}$$

This decimal answer is an approximation.  If you had enough digits a recurring fraction would appear.  

$${\frac{{\mathtt{4}}}{{\mathtt{523}}}} = {\mathtt{0.007\: \!648\: \!183\: \!556\: \!405\: \!4}}$$

$${\mathtt{0.007\: \!648\: \!183\: \!556\: \!405\: \!4}}$$  is your answer.

I'm not letting you have points for this Dragon!
