    This puzzle can be solved directly using the [[ SubsitutedDivision() ]] solver from the enigma.py library.

    Here is a run file that executes in 95ms.

    Run: [ @repl.it ]

    #!/usr/bin/env python -m enigma -r
    
    SubstitutedDivision
    
    "txbmt / gx = kpy"
    
    "txb - tkp = gt"
    "gtm - abm = ad"
    "adt - tpy = tm"
    

    Solution: The correct sum is: 17961 ÷ 37 = 485 (remainder 16).

    Those letters-for-digits puzzles with a random jumble of letters are just so unimaginative.
    We could have had DREAD / OR = SOB, which is what I do every time I see one by Emmet.
