As you deal the cards, the first 7 cards will form the 7 columns of the tableau. The eighth card distributed will go into the second column, since the first column has its 1 and only card, and the ninth card will go into the third column. You continue this process until 28 cards are dealt and the last column has 7 cards in it.
The tableau should now be cascaded downwards such that they form a reverse staircase from the left towards the right. Now, flip over the last card in each column so it's face up.
All leftover cards not dealt in the tableau become your stockpile, where you'd turn over the first card and begin playing the game. Now your game of solitaire is set up, and you're ready to play!
