1. We must divide 10 82 41 in groups of 2 digits, starting from the right. 

2. We find the square root of the number 10 which is 3, and we put it up to the right. Its square is 9 and we put it under the number 10. We subtract and we obtain 1. 

3. To the right of the number 1, we down the group 82. Then, we separate by a point the last number on the right (2). Under the root 3, we write the double of the root (6). The 18 is divided by 6 and we have 3. We will try to see if it the 3 is correct. We put the 3 to the right of the 6 and we have 63. We multiply it by 3 and we have 189, which is greater than 182. So the 3 is too great and we will take the 2. We put the 2 together to the 6, resulting in 62 

4. We multiply the number 62 (.) by the last obtained number (2) and we have 124. This number is put under the number 182 and we subtract, resulting in 58. We put the 2 in the upper part next to the 3, resulting in 32. 

5. Then, next to the number 58 we take down the group 41 and we separate with a point the last number that is 1, resulting in 584. Under 62.2 we put a line. We calculate the double of 32 which is 64. We divide 584 by 64, resulting in 9. We put this 9 next to 64, resulting in 649. We put the number 9 with number 32, obtaining 329. 

6. We multiply the resulting number 649 by the number 9, resulting 649 x 9 = 5841. We put this number on the down left part, under 5841 and we found the difference. The remainder is 0. The number 329 that is in the upper right part is the exact square root of the number 108241. To verify that the operation is correct, we find 329 x 329. As the result is 108241, we conclude that the square root is well done. To do the test of the square root, we find the square root and we add the rest. The sum must be equal to the given number.
