In Korean number system, the thousand delimiter is "," and decimal point delimiter is "." And we usually don't write below decimal point in Korean currency. 1.329.187,00 원 => 1,329,187.00 원 = 1,329,187 원 = 백삼십이만 구천백팔십칠 원 Refer to for reading big numbers https://www.italki.com/question/312097

In Korean we write numbers the same way as the English speaking countries do, using three digit grouping. In important documents, we may write the figure both as a number and as a Korean word, as in 1,000,000 and 백만. The reading of numbers is a little complicated because we use values corresponding to 10, 100, 1,000, 10,000, and at every fourth digit thereafter instead of every third as in the international standard. So we have 십(10), 백(100), 천(1,000), 만(10,000), 억(100,000,000) and so on, as follows. - 0,1..9 = 영(0), 일, 이, 삼, 사, 오, 육, 칠, 팔, 구(9). - 10(십), 100(백=hundred), 1,000(천=thousand)),10,000(만). - 100,000(십 만), 1,000,000(백 만=million), 10,000,000(천 만), 100,000,000(억), 1,000,000,000(십 억=billion), ... So 1,329,187 is read as 백삼십이 만 구천백팔십칠 (= 132만 9,187). Another example: 1,234,567,890 (2 is at 억, and 6 at 만), so it is 십이 억 삼천사백오십육 만 칠천팔백구십 (= 12억 3,456만 7,890). You'll need to get a firm grasp of the lowest units 십, 백, and 천, as they are repeated throughout. I'm not sure if this answers your question. If not, please let me know.
