See below how to convert 1 000 001 170(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 1 000 001 170 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;
  • 1 000 001 170 ÷ 2 = 500 000 585 + 0;
  • 500 000 585 ÷ 2 = 250 000 292 + 1;
  • 250 000 292 ÷ 2 = 125 000 146 + 0;
  • 125 000 146 ÷ 2 = 62 500 073 + 0;
  • 62 500 073 ÷ 2 = 31 250 036 + 1;
  • 31 250 036 ÷ 2 = 15 625 018 + 0;
  • 15 625 018 ÷ 2 = 7 812 509 + 0;
  • 7 812 509 ÷ 2 = 3 906 254 + 1;
  • 3 906 254 ÷ 2 = 1 953 127 + 0;
  • 1 953 127 ÷ 2 = 976 563 + 1;
  • 976 563 ÷ 2 = 488 281 + 1;
  • 488 281 ÷ 2 = 244 140 + 1;
  • 244 140 ÷ 2 = 122 070 + 0;
  • 122 070 ÷ 2 = 61 035 + 0;
  • 61 035 ÷ 2 = 30 517 + 1;
  • 30 517 ÷ 2 = 15 258 + 1;
  • 15 258 ÷ 2 = 7 629 + 0;
  • 7 629 ÷ 2 = 3 814 + 1;
  • 3 814 ÷ 2 = 1 907 + 0;
  • 1 907 ÷ 2 = 953 + 1;
  • 953 ÷ 2 = 476 + 1;
  • 476 ÷ 2 = 238 + 0;
  • 238 ÷ 2 = 119 + 0;
  • 119 ÷ 2 = 59 + 1;
  • 59 ÷ 2 = 29 + 1;
  • 29 ÷ 2 = 14 + 1;
  • 14 ÷ 2 = 7 + 0;
  • 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.

1 000 001 170(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 000 001 170 (base 10) = 11 1011 1001 1010 1100 1110 1001 0010 (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)
