Uma solução seria esta:(não parece bom, mas funciona)
SELECT
TRIM(TRAILING '0' FROM
TRIM(TRAILING '1' FROM
TRIM(TRAILING '2' FROM
TRIM(TRAILING '3' FROM
-- ...
TRIM(TRAILING '8' FROM
TRIM(TRAILING '9' FROM name)))))) AS name
FROM your_table
Então você pode selecionar com GROUP BY do resultado:
SELECT name, count(*) AS frequency FROM (
-- previous select
) AS t
GROUP BY name
