We look at the division of 21296129 by 71 
We're looking to find how many times 71 goes into 21296129.

Advancing to step 1:
71 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 71

Going ahead to step 2:
When dividing 21 by 71, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 71

Going ahead to step 3:
When dividing 212 by 71, we get 2 with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 142 from 212 and we're left with 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 71

Advancing to step 4:
The number 71 fits into 709 9 times, leaving a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 639 from 709 to get 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 71

Step 5:
The number 71 fits into 706 9 times, leaving a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 299.0
If we take 639 away from 706, we end up with 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 71

Going ahead to step 6:
If we divide 671 by 71, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 2999.0
Subtract 639 from 671 to get 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 71

Step 7:
71 goes into 322 4 times with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 29994.0
Subtracting 284 from 322 leaves us with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 71

Step 8:
The number 71 fits into 389 5 times, leaving a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 299945.0
Subtract 355 from 389 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 71, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 299945.4
Deduct 284 from 340 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 71 is 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 299945.47
Subtracting 497 from 560 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 11:
If we divide 630 by 71, we get 8 and a remainder of 62.
The next digit of our result is 8. 
Result so far: 299945.478
If we subtract 568 from 630, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
If we divide 620 by 71, we get 8 and a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 299945.4788
Subtracting 568 from 620 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 299945.4788 with a balance of 0.00052.
