I wrote down a 2-digit number and a 5-digit number and then carried out a long division.
I then erased all of the digits in the calculation, other than the 1’s, and so finished up with the image above.
If I told you how many different digits I had erased, then you should be able to work out my two original numbers.
What were my two original numbers?
