He died falling down the stairs after a long career in the army.

"We helped her into bed before she could fall down the stairs and hurt herself."

I fell down the stairs and out of the door.

She was pulling so hard on his hand, he had to either go with her or fall down the stairs.

Before she could do so, he fell down the stairs.

"I want to know how you managed to fall down the stairs."

And maybe you'll fall down the stairs when they do.
