1000000-100+500+754+8-90000÷49394×5

Let's break down the calculation step by step:

1. Calculate \( 90000 ÷ 49394 \): \[ 90000 ÷ 49394 \approx 1.821 \]

2. Now, multiply that result by 5: \[ 1.821 × 5 \approx 9.105 \]

3. Now substitute this back into the original expression: \[ 1000000 - 100 + 500 + 754 + 8 - 9.105 \]

4. Perform the addition and subtraction from left to right:

   • Start with \( 1000000 - 100 = 999900 \)
   • Then \( 999900 + 500 = 1000400 \)
   • Next \( 1000400 + 754 = 1001154 \)
   • Then \( 1001154 + 8 = 1001162 \)
   • Finally, \( 1001162 - 9.105 \approx 1001152.895 \)

So, the final result is approximately: \[ \text{1001152.895} \]
