It's canot be 8 because: Call Z= abcd - 8Y, Z have 2 digit 10Z +e -7Y = 3 digit The third number of quitient( call it is n) x Y = 3 digit and the subtraction of nY get 2 digit ,ít impossible So we got 97809. We know 9Y >= 1000, 8Y<1000 So Y =[112-124] I check and divinded is 12128316 Quote Link to comment Share on other sites More sharing options...

Your value for the quotient is very close. Check it, you may have transposed two digits. Expand Quote Link to comment Share on other sites More sharing options...
