Step 1:

Divide the number (40.96) by 2 to get the first guess for the square root .

First guess = 40.96/2 = 20.48

Step 2:

Divide 40.96 by the previous result. d = 40.96/20.48 = 2.

Average this value (d) with that of step 1: (2 + 20.48)/2 = 11.24 (new guess).

Error = new guess - previous value = 20.48 - 11.24 = 9.24.

9.24 > 0.001. As error > accuracy, we repeat this step again.

Step 3:

Divide 40.96 by the previous result. d = 40.96/11.24 = 3.6441281139.

Average this value (d) with that of step 2: (3.6441281139 + 11.24)/2 = 7.442064057 (new guess).

Error = new guess - previous value = 11.24 - 7.442064057 = 3.797935943.

3.797935943 > 0.001. As error > accuracy, we repeat this step again.

Step 4:

Divide 40.96 by the previous result. d = 40.96/7.442064057 = 5.5038494276.

Average this value (d) with that of step 3: (5.5038494276 + 7.442064057)/2 = 6.4729567423 (new guess).

Error = new guess - previous value = 7.442064057 - 6.4729567423 = 0.9691073147.

0.9691073147 > 0.001. As error > accuracy, we repeat this step again.

Step 5:

Divide 40.96 by the previous result. d = 40.96/6.4729567423 = 6.3278655537.

Average this value (d) with that of step 4: (6.3278655537 + 6.4729567423)/2 = 6.400411148 (new guess).

Error = new guess - previous value = 6.4729567423 - 6.400411148 = 0.0725455943.

0.0725455943 > 0.001. As error > accuracy, we repeat this step again.

Step 6:

Divide 40.96 by the previous result. d = 40.96/6.400411148 = 6.3995888784.

Average this value (d) with that of step 5: (6.3995888784 + 6.400411148)/2 = 6.4000000132 (new guess).

Error = new guess - previous value = 6.400411148 - 6.4000000132 = 0.0004111348.

0.0004111348 <= 0.001. As error <= accuracy, we stop the iterations and use 6.4000000132 as the square root.

Read it carefully and you will understand the way to get answer.
