Division Question

How many different solutions are there to this division? different letters stand for different digits and no number begins with zero.

JMO / UK = OK ( what are the numbers)

One solution.
JMO = OK*UK
K cannot be one, because K^2 = 1 = O,. repetition is not allowed.
Let K = 2. Then O = 4
So 42* U2 = JMO.
Product is three digits. U cannot be 3,neither 2. So try one
So 42*12 = 504.
Try other combination, if possible.

I think the complete set of solutions is:
$\begin{array}{c c c c c} J&M&O&U&K\\ 5&0&4&1&2\\ 8&9&6&1&4\\ 7&4&1&3&9\\ 9&3&1&4&9\\ \end{array}$

In the last set there is a repetition which is not allowed.

This is true! Strike that line from the solutions!

thanks for all the replies, is there a way solving it by equations, instead of solving it by trials
