Detailed Syllable Analysis:

Division Rules Applied:

1. Onset-Rime Division: The most common rule, dividing syllables based on the consonant onset and vowel-containing rime.
2. Vowel-Consonant-E Rule: Not applicable here, as there are no syllables ending in silent 'e'.
3. Consonant Cluster Rule: Consonant clusters are generally kept together in the onset or coda.

Minor variations in vowel quality (e.g., /iː/ vs. /ɪ/) might occur depending on regional accents, but these do not significantly alter the syllable division.
