equation solving - First two n such that $1355297$ divides$10^{6n+5}-54n-46$ for $n>0$

I have problem solving this equation, smallest n such that $1355297$ divides $10^{6n+5}-54n-46$. I tried everything using my scientific calculator, but I never got the correct results(!).and finally I gave up!. Could you help me find the first 2 solutions for this equation ? (thanks.)

Answer

$n_1 = 2331259$, $n_2 = 3776127$,

Obtained from this Mathematica code:

cf = Compile[{{m, _Integer}},
  Block[{n, a, b, p, counter = 0,result},
   result = ConstantArray[0, m];
   p = 1355297;
   n = 0;
   a = Mod[10^(5), p];
   b = 0;
   While[counter < m,
    n++;
    a = Mod[a 1000000, p];

    b = Mod[b - 54 , p];
    While[Mod[a + b - 46, 1355297] != 0,
     n++;
     a = Mod[a 1000000, p];
     b = Mod[b - 54 , p];
     ];
    counter++;
    result[[counter]] = n;
    ];
   result

   ],
  CompilationTarget -> "C"
  ];

cf[2]

{2331259, 3776127}
