NumberWiz example with the Big numbers freely chosen: 888

Hi fellow NumberWizards, I put to you the question: 
How do you add subtract, multiply and divide 6 9 10 51 69 85 to get 888.


Here's a solution:
888 = (85 + 6) * 9 + 69

NumberWiz example with the Big numbers freely chosen

Hi,
Here's a NumberWiz problem, where I've replaced the Big numbers with numbers of my own choice. In this case I've replaced 25, 50, 75 and 100 with 31, 51, 69 and 85. 
And now the problem is:
How do you add, subtract, multiply and divide 6 9 10 51 69 85 to get 888?
Would be nice to see a solution in the comments.
