What are the required steps to convert base 10 decimal system
number 1 478 963 171 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;
  • 1 478 963 171 ÷ 2 = 739 481 585 + 1;
  • 739 481 585 ÷ 2 = 369 740 792 + 1;
  • 369 740 792 ÷ 2 = 184 870 396 + 0;
  • 184 870 396 ÷ 2 = 92 435 198 + 0;
  • 92 435 198 ÷ 2 = 46 217 599 + 0;
  • 46 217 599 ÷ 2 = 23 108 799 + 1;
  • 23 108 799 ÷ 2 = 11 554 399 + 1;
  • 11 554 399 ÷ 2 = 5 777 199 + 1;
  • 5 777 199 ÷ 2 = 2 888 599 + 1;
  • 2 888 599 ÷ 2 = 1 444 299 + 1;
  • 1 444 299 ÷ 2 = 722 149 + 1;
  • 722 149 ÷ 2 = 361 074 + 1;
  • 361 074 ÷ 2 = 180 537 + 0;
  • 180 537 ÷ 2 = 90 268 + 1;
  • 90 268 ÷ 2 = 45 134 + 0;
  • 45 134 ÷ 2 = 22 567 + 0;
  • 22 567 ÷ 2 = 11 283 + 1;
  • 11 283 ÷ 2 = 5 641 + 1;
  • 5 641 ÷ 2 = 2 820 + 1;
  • 2 820 ÷ 2 = 1 410 + 0;
  • 1 410 ÷ 2 = 705 + 0;
  • 705 ÷ 2 = 352 + 1;
  • 352 ÷ 2 = 176 + 0;
  • 176 ÷ 2 = 88 + 0;
  • 88 ÷ 2 = 44 + 0;
  • 44 ÷ 2 = 22 + 0;
  • 22 ÷ 2 = 11 + 0;
  • 11 ÷ 2 = 5 + 1;
  • 5 ÷ 2 = 2 + 1;
  • 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.

1 478 963 171(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 478 963 171 (base 10) = 101 1000 0010 0111 0010 1111 1110 0011 (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)
