### Step 1: Start with the initial value
We begin with the number 505.

### Step 2: Subtract 50 from 505
\[ 505 - 50 = 455 \]

### Step 3: Subtract 5 from 455

### Step 4: Subtract another 50 from 450
\[ 450 - 50 = 400 \]

### Step 5: Subtract 5 from 400
\[ 400 - 5 = 395 \]

### Step 6: Subtract 5 from 395
\[ 395 - 5 = 390 \]

### Final Result
After performing all the subtractions, we find that:
\[ 505 - 50 - 5 - 50 - 5 - 5 = 390 \]
