98989898×99999999÷1010101÷11111111
=98×1010101×9×11111111÷1010101÷11111111
=98×9
=(100-2)×9
=900-18
=882
---------------------------------------------------
98989898*99999999/1010101/11111111
=（98*1010101*9*11111111）/（1010101*11111111）
=98*9
=（98*（10-1）
=980-98
=882

-----------------------------------------------------------
98989898×99999999÷1010101÷11111111
=(98989898÷1010101)×(99999999÷11111111)
=98×9
=882
