I was asked in a comment on my previous post, How to convert your fiat to steem, about sending steem from your Steemit account back out to an exchange. So here is how you send it out to the Binance exchange.
Open your Binance account, and when you click on Funds - Deposits and then choose steem, you should see this:

Then click I understand. Continue, and you will see your STEEM Deposit Address and STEEM Deposit MEMO.

So next open your Steemit wallet and click here:

Then choose Transfer.

Fill in your Binance STEEM Deposit Address and STEEM Deposit MEMO along with the amount of steem you are transferring:
Click Submit and you will then be asked for your private key.
I do hope this is also of help to others. Thank you.
