What are the required steps to convert base 10 decimal system
number 1 166 755 789 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;
  • 1 166 755 789 ÷ 2 = 583 377 894 + 1;
  • 583 377 894 ÷ 2 = 291 688 947 + 0;
  • 291 688 947 ÷ 2 = 145 844 473 + 1;
  • 145 844 473 ÷ 2 = 72 922 236 + 1;
  • 72 922 236 ÷ 2 = 36 461 118 + 0;
  • 36 461 118 ÷ 2 = 18 230 559 + 0;
  • 18 230 559 ÷ 2 = 9 115 279 + 1;
  • 9 115 279 ÷ 2 = 4 557 639 + 1;
  • 4 557 639 ÷ 2 = 2 278 819 + 1;
  • 2 278 819 ÷ 2 = 1 139 409 + 1;
  • 1 139 409 ÷ 2 = 569 704 + 1;
  • 569 704 ÷ 2 = 284 852 + 0;
  • 284 852 ÷ 2 = 142 426 + 0;
  • 142 426 ÷ 2 = 71 213 + 0;
  • 71 213 ÷ 2 = 35 606 + 1;
  • 35 606 ÷ 2 = 17 803 + 0;
  • 17 803 ÷ 2 = 8 901 + 1;
  • 8 901 ÷ 2 = 4 450 + 1;
  • 4 450 ÷ 2 = 2 225 + 0;
  • 2 225 ÷ 2 = 1 112 + 1;
  • 1 112 ÷ 2 = 556 + 0;
  • 556 ÷ 2 = 278 + 0;
  • 278 ÷ 2 = 139 + 0;
  • 139 ÷ 2 = 69 + 1;
  • 69 ÷ 2 = 34 + 1;
  • 34 ÷ 2 = 17 + 0;
  • 17 ÷ 2 = 8 + 1;
  • 8 ÷ 2 = 4 + 0;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 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.

1 166 755 789(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 166 755 789 (base 10) = 100 0101 1000 1011 0100 0111 1100 1101 (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)
