One method supported by most databases is the use of recursive CTEs. The exact syntax might vary, but the idea is:
with cte as (
select loannum, document, cnt_repeat, 1 as lev
from t
union all
select loannum, document, cnt_repeat, lev + 1
from cte
where lev < cnt_repeat
)
select loannum, document, cnt_repeat
from cte;
