BTW before anyone gets any bright ideas about trying this in real life:
This is called "layering" and is often a criminal offense [1] and banks have effective means to detect it (as they are required to by law). In particular they are highly attuned to flows of money that seem to split up large bunches of cash into smaller amounts that the would-be money launderer thinks will be below some static threshold. The detections which catch this have been in all banks I've ever worked with (since around 2010 when I first touched on doing any anti-moneylaundering work and they were very mature and well-established by then)[2].
You are highly unlikely to get away with it unless you have already been doing it for some time or know someone who has and is willing to share their techniques.
[1] Obviously or not it's only a criminal offense if you doing it to evade detection (eg for tax fraud or to avoid paying say a court settlement or something) or are otherwise laundering the proceeds of crime - that sort of thing. If you're just doing it for your own amusement it will probably get you added to a watchlist of suspicious accounts at your bank that they will monitor extra closely and may get you investigated by various financial crime enforcement organisations. Which even if you haven't done anything wrong I imagine would be stressful and time-consuming.
[2] To give people who are not part of this world the idea, at least in the UK and US all employees of any kind of deposit-taking institution are required by regulators to have an annual anti-moneylaundering training which covers layering and how to detect it. So literally every bank employee should know what this pattern looks like and should be on the look out for it.
Layering is a step in money laundering where layers of legitimacy are added as money moves around. Structuring is breaking larger transactions into smaller transactions in order to avoid detection. Smurfing is also similar to structuring and honestly I don't understand the difference well enough to explain, but they are often used interchangeably in my experience.
