What is x when 64 divided by x equals 19?

To find the answer, just divide the dividend by the quotient: 64 ÷ 19 = 3.3684210526316

To prove this, let's compute 64 divided by 3.3684210526316: $\frac{64}{3.3684210526316} = 19$

How does it work?

Asking what the value of x could be when 64 divided by x gives a result of 19, is equivalent to solving the following equation:

$\frac{64}{x} = 19$

Multiply both sides by x: $\frac{64 x}{x} = 19 x$
$\frac{64 x}{x}$ is equivalent to $\frac{x}{x} \times 64$ , which simplifies to $1 \times 64$ (or just $64$ ).
Thus, the equation becomes: $64 = 19 x$
To find x, divide both sides by 19: $\frac{64}{19} = \frac{19 x}{19}$
Which gives, after simplification: $3.3684210526316 = x$ (or $x = 3.3684210526316$ )

So, if the dividend is 64 and the quotient is 19, the divisor is 3.3684210526316.
