Bash - Sed / Awk replace string with new string

I have a file with lines similar to the one below, and I want to replace all things between the “steps” and “-” with a new line:

- name: Change It uid: Change It_TRANS_App - Web type: TRANSACTION steps: 02 - name: Change It 1 type: BSTEP uid: Step 1_STEP_Change It_TRANS_App -strong text Web rules:

I tried using awk like:

echo $string | awk {'gsub(/steps:.*?-/ , 'steps:\n-' )'; print $0}

However, I get the following error:

awk: {gsub(/steps:.*?-/ , steps:n- )
awk:                          ^ syntax error
awk: fatal: 0 is invalid as number of arguments for gsub

I also tried with sed:

sed -r 's:/\bsteps:\b.*?-/\n/' stringfile.txt > output.txt

and deleting ":":

sed -r 's/\bsteps.*?-/\n/' stringfile.txt > output.txt

In the first case, I get an error:

sed: -e expression #1, char 28: unterminated `s' command

And with the second sed, I delete many other things that it should not do.

[Edit] As you guys told me, I forgot to deliver the expected result, I thought it would be easy, but I'm not good. I want to break because the new line only cuts out the word immediately after the "step", in this case it will be "02". This will be the first appearance of a "-":

- name: Change It uid: Change It_TRANS_App - Web type: TRANSACTION steps:
- name: Change It 1 type: BSTEP uid: Step 1_STEP_Change It_TRANS_App -strong text Web rules:

sed -r 's/\bsteps[^-]*-/\n-/' file

:

$ sed -r 's/\bsteps[^-]*/\n/' file
- name: Change It uid: Change It_TRANS_App - Web type: TRANSACTION 
- name: Change It 1 type: BSTEP uid: Step 1_STEP_Change It_TRANS_App -strong text Web rules:

:

awk '{gsub(/steps:.*-/,"steps:\n-");print $0}' <<< "$sting"
- name: Change It uid: Change It_TRANS_App - Web type: TRANSACTION steps:
-strong text Web rules:

:

awk '{gsub(/steps:.*-/,"steps:\n-")}1' <<< "$sting"

Ref Eds comments:

awk '{gsub(/steps:[^-]*-/,"steps:\n-")}1' t
- name: Change It uid: Change It_TRANS_App - Web type: TRANSACTION steps:

- :

echo $string | perl -pe 's/(.*steps:).*(-.*)/$1\n$2/'
