'Get first 200 String ,set sequence and increment it if the string is more than 200

I am trying to solve this usecase where I have below json (NOtepadOverflow Data)

"notepadOverflowData": [
            {
                "sectionSequenceNumber": "01",
                "sectionText": "ABCDEFG,HIJKLMNOPQRSTAB,CDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRS1 nationality +"
            },
            {
                "sectionSequenceNumber": "02",
                "sectionText": "ABCDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRSTDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRS1 nationality +"
            }   ,
            {
                "sectionSequenceNumber": "99",
                "sectionText": "ABCDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRSTDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRSTABCDEFGHIJKLMNOPQRS1 nationality +"
            }   
        ],

In this, I need to get first 200 characters and set it in sectionText, and in sectionSequenceNumber it should start from "01". now If the mainString is > 200 , cut it and set that secondSubstring in second block - sectionText(will be next 200) and sectionSequenceNumber = "02" , so on and so forth.

I have tried below things but it is not giving expected result - String nationality ="01,789,115,243,829,565,371,182,647,4435910257262248077394052327956158518390755253526164992046808288158147741133875811175906263458023936812929164522298298102045746231643365172017152941946079512878050984287357708374166217380767662303239772860984374849481114923522772038584914212671591311297:001,789,115,243,829,565,371,182,647,443,591,025,726,224,807,739,405,232,795,615,851,839,075,525,352,616,499,204,680,828,815,814,774,113,387,581,117,590,626,345,802,393,842873577083741662173807676623032397728609843748494811149235227720385849142126715913112839,075,525,352,616,499,204,680,828,815,814,774,113,387,581,117,590,626,345,802,393,842873577083741662173807676623032397728609843748494811149235227720385849142126715913112";

String nationalityTrimName = nationality.substring(0, Math.min(nationality.length(), 200));
            String lastStr = nationality.substring(countIncrement, Math.min(nationality.length(), nationality.length() - 1));
            do {
                notepadOverflowData.setSectionSequenceNumber(count);//1
                notepadOverflowData.setSectionText(nationalityTrimName);
                notepadOverflowDataList.add(notepadOverflowData);

                while (lastStr.length() >= 200) {
                    if (lastStr.length() >= 200) {
                        lastStr = lastStr.substring(countIncrement, Math.min(lastStr.length(), lastStr.length() - 1));
                        counter = Integer.parseInt(count);
                        Integer i = counter + 1;
                        sequenceNumber = String.format("%02d", i);
                        buildNotepadEntryReq(notepadOverflowDataList, notepadOverflowData1,

                    }else {
                        buildNotepadEntryReq(notepadOverflowDataList, notepadOverflowData1, sequenceNumber,
                                lastStr,countIncrement);
                    }
                    if(!StringUtils.isEmpty(lastStr) && lastStr.length() > 200) {
                        countIncrement = countIncrement + 200;
                        cnt = Integer.parseInt(sequenceNumber);
                        Integer i = cnt+1;
                        sequenceNumber = String.format("%02d",i);
                    }

                }

            /*char last = lastStr.charAt(lastStr.length() - 1);
            lastStr = lastStr.substring(200, Math.min(lastStr.length(), last));*/
                notepadOverflowDataList.add(notepadOverflowData1);
            } while (nationalityTrimName.length() > 200);
        }

private void buildNotepadEntryReq(List<NotepadOverflowData> notepadOverflowDataList,
                                      NotepadOverflowData notepadOverflowData1, String sequenceNumber,
                                      String lastSecondStr,int countIncrement) {
        if (sequenceNumber.length() <= 99) {
            notepadOverflowData1.setSectionSequenceNumber(sequenceNumber);
        } else {
            logger.error("Sequence Number is more than 99");
        }
        notepadOverflowData1.setSectionText(lastSecondStr);
        notepadOverflowDataList.add(notepadOverflowData1);
    }

I am getting output as -

"notepadOverflowData": [
        {
            "sectionSequenceNumber": "01",
            "sectionText": "Customer additional Nationalities :01,789,115,243,829,565,371,182,647,4435910257262248077394052327956158518390755253526164992046808288158147741133875811175906263458023936812929164522298298102045746231"
