This a step by step guide on withdrawing steemdollars from your steemit.com account to bittrex.com
First off you need an account at Bittrex.com
It's quite intuitive and similar to sign ups on most sites so we won't cover it

Step 2 - From the SBD market page, and click the wallet tab.
Click the new address button if the deposit fields are blank.
Copy (CTRL+C or right click) your memo field as this is require by bittrex to identify your transaction and credit your bittrex account.
Step 3 - On Steemit.com, while logged in click the head in the corner and select wallet from the drop down list
Step 4 - From the wallet screen, click the arrow on your Steem dollars and select transfer from the drop down list
Step 5 - Fill out the transfer popup

Once you have these 4 items selected, click transfer and the transaction will start
Step 6 - Verify your deposit
You can see your balance from the market page or go to the wallet tab and see your pending/complete deposits, the bitshares network is speedy! So you should see it almost immediately.
If there's nothing after 10 minutes you might have something wrong with your memo field. Contact support@bittrex.com immediately or join their live chat slack.bittrex.com, or the help desk https://bittrex.zendesk.com/hc/en-us
Now your Steem dollars (SBD) on bittrex exchange! If you want to transfer $STEEM the process is very similar but your deposit memo field will be different. Hope this helps and happy steeming
