You may find the following a shorter example:
#!/bin/sh
lscpu |awk -F : '($1=="CPU MHz") {printf "%3.2fGHz\n", $2/1000}'
Note that, on my system, using an AMD CPU and lscpu version 2.27.1 on ubuntu server 16.04 (64 bit) I have lines in the output as follows:
CPU MHz: 4000.000
CPU max MHz: 4000.0000
CPU min MHz: 1400.0000
The awk command uses ":" as the field separator. It looks for the line starting "CPU MHz" and then simply prints the value over 1000 (convert MHz to GHz) using 3.2 format -- three significant figures with two decimal places.
From your question, you appear to be looking for "CPU-frequentie" is the lscpu output. I don't know what the output of your lscpu looks like, but I assume that you might need to substitute "CPU-frequentie" for "CPU MHz" in the awk line
For completeness, the output I get on my system is:
4.00GHz
