Let x be the number, (435*100,000 + 521)*x = adasd...fsh791 So, last digit of x must be 1. The answer is clearly 871, but I did this problem with logic and it's really tough to explain logic unless your communication skills are really impressive. So... I am gonna tag @FoolForMath and @Mr.Math to see if they know some trick or the method you mentioned above.

but it doesn't matter, just get the 521 separately and then multiply it my x (the assumed number).dw:1332944499486:dw

871 is the answer, if you know the one line multiplication then this problem is a 10 seconder ;)
