# 999 in Binary

999 in binary is 1111100111. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 10 bits to represent 999 in binary. In this article, let us learn how to convert the decimal number 999 to binary.

## How to Convert 999 in Binary?

**Step 1:** Divide 999 by 2. Use the integer quotient obtained in this step as the dividend for the next step. Repeat the process until the quotient becomes 0.

Dividend | Remainder |
---|---|

999/2 = 499 | 1 |

499/2 = 249 | 1 |

249/2 = 124 | 1 |

124/2 = 62 | 0 |

62/2 = 31 | 0 |

31/2 = 15 | 1 |

15/2 = 7 | 1 |

7/2 = 3 | 1 |

3/2 = 1 | 1 |

1/2 = 0 | 1 |

**Step 2:** Write the remainder from bottom to top i.e. in the reverse chronological order. This will give the binary equivalent of 999.

Therefore, the binary equivalent of decimal number 999 is 1111100111.
