What is x when 87 divided by x equals 14?

To find the answer, just divide the dividend by the quotient: 87 ÷ 14 = 6.2142857142857

To prove this, let's compute 87 divided by 6.2142857142857: $\frac{87}{6.2142857142857} = 14$

How does it work?

Asking what the value of x could be when 87 divided by x gives a result of 14, is equivalent to solving the following equation:

$\frac{87}{x} = 14$

Multiply both sides by x: $\frac{87 x}{x} = 14 x$
$\frac{87 x}{x}$ is equivalent to $\frac{x}{x} \times 87$ , which simplifies to $1 \times 87$ (or just $87$ ).
Thus, the equation becomes: $87 = 14 x$
To find x, divide both sides by 14: $\frac{87}{14} = \frac{14 x}{14}$
Which gives, after simplification: $6.2142857142857 = x$ (or $x = 6.2142857142857$ )

So, if the dividend is 87 and the quotient is 14, the divisor is 6.2142857142857.
