Input in the third row, maximum 524287. It needs heavy optimization:
for a number N, it takes a little more than N seconds to start the
output, so don't try huge numbers.
Example with 42:

Ah yes! Combine this, binary adder/subtracter, and the binary multiplier, and we can make a calculator! We still don't have the binary divider though.

My version - avoids the operator having to scroll the level, so it's

"easier to see what's going on" because it's all on the screen at the
same time!
It processes a number up to 1599999 as binary input on the top row.
The time taken is constant, whatever number is entered. As there is
only space for 6 digits on the output, a black dot is painted at the
end to indicate an overflow (i.e. a first digit of 1). There's a bug I
couldn't be bothered to fix (as I only noticed it as I was writing
this, having already copy-pasted the level into the message box) which
causes it to crash if you ask it to process a number equal or greater
than 1600000. Easiest fix would be to put some other object over where
the highest bit would go, and declare the maximum input to be 1048575.
Example shown has input 1234567.
The intermediate representation is BCD ("binary coded decimal"). It
takes more time to get the "human-readable" version than to convert
the number to a form of decimal in the first place....

As well as this bug, there's also a couple of "deliberate" errors for

you to find, which only show up when there are certain digits in
certain places... (a couple of wires missing from the central "None")
