Can someone help me? I have a string:

```
This is example. This is example. This is example. This is example. This is example. This is example. This is example. This is example. This is example.

```

I want to cut 35 characters of it and the rest of string move to bottom line. After that I want to cut 35 characters of string in second line and rest of string move to third line. After that I want cut 35 characters of string in third line and move rest of string to fourth line. It should look like this:

```
This is example. This is example. T
his is example. This is example. Th
is is example. This is example. Thi
s is example. This is example. This
is example.

```

I tried to do thing with substring function but I have no idea how to move down rest of my string.
