71 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 71

Moving on to step 3:
The number 71 fits into 210 2 times, leaving a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 68 after subtracting 142 from 210.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 71

Going ahead to step 4:
71 can be fit into 686 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 47 after subtracting 639 from 686.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 71

On to step 5:
If we divide 475 by 71, we get 6 and a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 296.0
Subtract 426 from 475 to get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 71

On to step 6:
71 goes into 492 6 times with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 2966.0
Subtract 426 from 492 to get 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 71

Advancing to step 7:
The number 71 fits into 663 9 times, leaving a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 29669.0
If we subtract 639 from 663, we get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 71

On to step 8:
If we divide 240 by 71, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 296693.0
The remainder is 27 after subtracting 213 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 71, we get 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 296693.3
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
71 goes into 570 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 296693.38
Subtracting 568 from 570 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
71 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 296693.38
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
71 can be fit into 200 2 times, resulting in a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 296693.3802
If we subtract 142 from 200, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
71 can be fit into 580 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 296693.38028
Subtracting 568 from 580 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 71 fits into 120 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 296693.380281
Subtract 71 from 120 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 15:
If we divide 490 by 71, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 296693.3802816
Subtracting 426 from 490 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
When dividing 640 by 71, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 296693.38028169
If we subtract 639 from 640, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 296693.38028169 with a balance of 1e-09.
