See below how to convert 1 007 000 857(10), the unsigned base 10 decimal system number to base 2 binary equivalent

What are the required steps to convert base 10 decimal system
number 1 007 000 857 to base 2 unsigned binary equivalent?

  • A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.

1. Divide the number repeatedly by 2:

Keep track of each remainder.

Stop when you get a quotient that is equal to zero.


  • division = quotient + remainder;
  • 1 007 000 857 ÷ 2 = 503 500 428 + 1;
  • 503 500 428 ÷ 2 = 251 750 214 + 0;
  • 251 750 214 ÷ 2 = 125 875 107 + 0;
  • 125 875 107 ÷ 2 = 62 937 553 + 1;
  • 62 937 553 ÷ 2 = 31 468 776 + 1;
  • 31 468 776 ÷ 2 = 15 734 388 + 0;
  • 15 734 388 ÷ 2 = 7 867 194 + 0;
  • 7 867 194 ÷ 2 = 3 933 597 + 0;
  • 3 933 597 ÷ 2 = 1 966 798 + 1;
  • 1 966 798 ÷ 2 = 983 399 + 0;
  • 983 399 ÷ 2 = 491 699 + 1;
  • 491 699 ÷ 2 = 245 849 + 1;
  • 245 849 ÷ 2 = 122 924 + 1;
  • 122 924 ÷ 2 = 61 462 + 0;
  • 61 462 ÷ 2 = 30 731 + 0;
  • 30 731 ÷ 2 = 15 365 + 1;
  • 15 365 ÷ 2 = 7 682 + 1;
  • 7 682 ÷ 2 = 3 841 + 0;
  • 3 841 ÷ 2 = 1 920 + 1;
  • 1 920 ÷ 2 = 960 + 0;
  • 960 ÷ 2 = 480 + 0;
  • 480 ÷ 2 = 240 + 0;
  • 240 ÷ 2 = 120 + 0;
  • 120 ÷ 2 = 60 + 0;
  • 60 ÷ 2 = 30 + 0;
  • 30 ÷ 2 = 15 + 0;
  • 15 ÷ 2 = 7 + 1;
  • 7 ÷ 2 = 3 + 1;
  • 3 ÷ 2 = 1 + 1;
  • 1 ÷ 2 = 0 + 1;

2. Construct the base 2 representation of the positive number:

Take all the remainders starting from the bottom of the list constructed above.

1 007 000 857(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 007 000 857 (base 10) = 11 1100 0000 0101 1001 1101 0001 1001 (base 2)

Spaces were used to group digits: for binary, by 4, for decimal, by 3.


How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base 10 to base 2

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
  • 55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
