Hi For big numbers (more than about 16 digits), python wrong calculate division, but calculating mod (%) is correct. I write a sample code of manual division in file. Thanks |

The `/` operator does true division, which means the result will be a `float` rather than an `int`. When the resultant float is large enough, precision will be lost. You can use the `//` operator for floor (integer) division, where the result will remain as an integer. |
