<p><strong>Step 6:</strong>Now choose a number such that when placed at the end of 2, a 2-digit number will be formed. Multiply that particular number by the resultant number to get a number less than 1. Here, that number is 0. 20×0=0<1.</p>

<p><strong>Step 7:</strong>Subtract 15-0=15. Add a decimal point after the new quotient 10, again, bring down two zeroes and make 15 as 1500. Simultaneously add the unit’s place digit of 20, i.e., 0 with 20. We get here, 20. Apply Step 5 again and again until you reach 0. </p>

<p>We will show two places of precision here, and so, we are left with the remainder, 17271 (refer to the picture), after some iterations and keeping the division till here, at this point </p>
