let's think about it, let's divide say hmmm 15 by 0, in a fraction
![\bf \cfrac{\textit{part of a pie}}{\textit{whole pie}}\qquad \cfrac{15}{0}\implies \cfrac{\textit{taking 15 pieces}}{\textit{from a whole pie that's 0, or not there}}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/i7cwz1vjpeez4203kg41tde4e18nxe6xbi.png)
now, how can you take any pieces of a pie that's non-existent? I mean that requires magic!!.
now, let's do it using a simple long division, 15 ÷ 0, so 0 is the divisor, anything times 0 is 0, what is our first digit in the quotient to get 15? 0 * 15 = 0, 0 * 1,000,000 = 0, there isn't any number we can possible use to get a quotient.
