What is x when 64 divided by x equals 86?

To find the answer, just divide the dividend by the quotient: 64 ÷ 86 = 0.74418604651163

To prove this, let's compute 64 divided by 0.74418604651163: $\frac{64}{0.74418604651163} = 86$

How does it work?

Asking what the value of x could be when 64 divided by x gives a result of 86, is equivalent to solving the following equation:

$\frac{64}{x} = 86$

Multiply both sides by x: $\frac{64 x}{x} = 86 x$
$\frac{64 x}{x}$ is equivalent to $\frac{x}{x} \times 64$ , which simplifies to $1 \times 64$ (or just $64$ ).
Thus, the equation becomes: $64 = 86 x$
To find x, divide both sides by 86: $\frac{64}{86} = \frac{86 x}{86}$
Which gives, after simplification: $0.74418604651163 = x$ (or $x = 0.74418604651163$ )

So, if the dividend is 64 and the quotient is 86, the divisor is 0.74418604651163.
