This works

| s1 s2 |

s1 := 'abcdefghijk'.

s2 := String streamContents: [:s || in len |

in := ReadStream on: s1.

len := 0.

[in atEnd] whileFalse: [

s nextPut: in next.

len := len + 1.

(in atEnd not and: [ (len \\ 3) = 0]) ifTrue: [ s space ] ] ]

Hello,

I wonder if it is possible in Pharo to divide a string in lets say part
of 3.
so this : 'abcdefgh'

would be 'abc def gh`

Do you really want a single string with spaces inserted or do you want a collection of substrings, each three characters (or less, for the last one)?

I need a single string with spaces inserted.
So maybe I have formulate my question wrong. Very difficult if English is not your mother language and you were bad at school in languages a very very long ago.
