Hello,

 

I have a question about the change of radix, for example:

 

Convert 1020304 base 10 into base 7:

 

1020304 / 7 = 145757 r 5

145757 / 7 = 20822 r 3

20822 / 7 = 2974 r 4

2974 / 7 = 424 r 6

424 / 7 = 60 r 4

60 / 7 = 8 r 4

8 / 7 = 1 r 1

1 / 7 = 0 r 1 => 11446435

 

There is a tip to divide a big number with a little number?, is posible with a simple calculator get the remainders from a divition like that?

Substract the whole number before the dot then multiply by seven again. Not sure if that is really what you asked for, though.

"145757 r 5" ist just a way to write "145757 + 5/7", after all.
