What your wallet holds are addresses. These addresses can occur in the Bitcoin block chain, which can - at its simplest - be seen as a big database of balances for each Bitcoin address. Your wallet also holds a private key for each address, which can be seen as the password needed to spend the balance that is accredited to the corresponding address. When you spend some bitcoins, you send them from one of your addresses to another address.

Only the person that owns the private key corresponding to the address, can spend the bitcoins on its balance. Now, that still not explains how bitcoins can be divided into smaller fractions. In fact, the Bitcoin protocol does not really work with the unit bitcoin, but with a smaller unit, called satoshi.

Your understanding of bitcoins is incorrect. A bitcoin is only a number in a ledger, called the blockchain. When someone receives bitcoins, a transaction is added to their ledger which shows them as having received the bitcoins. When they send out bitcoins, a transaction is added to their ledger which shows them as having given away bitcoins.

You create a bitcoin "address" which is just a public key you hold the private side which is proof that you own the address. You can have an unlimited amount of public keys. At all times, the blockchain contains information that defines how many BTC each address owns. The blockchain is like an accounting journal. Everyone knows how many BTC every address owns at any one time. However, you send to more than one recipient, one of those recipients can be yourself.

The address at the left sent 1. This is also how you make "change". You send a portion of the owned BTC to the recipient, and the rest to yourself and this also serves to further anonymize transactions. Sign up to join this community.
