71259947 ÷ 809 
Our goal is to divide 71259947 by 809.

Let's proceed to step 1:
If we divide 7 by 809, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 809

On to step 2:
When dividing 71 by 809, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 809

Step 3:
If we divide 712 by 809, we get 0 and a remainder of 712.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 712, we end up with 712.
Bring next digit (5) of the dividend behind the 712 and repeat the process: 7125 / 809

Going ahead to step 4:
When dividing 7125 by 809, we get 8 with a remainder of 653.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 653 after subtracting 6472 from 7125.
Append the next digit (9) from the dividend to 653 and continue with: 6539 / 809

Let's proceed to step 5:
If we divide 6539 by 809, we get 8 and a remainder of 67.
The next digit of our result is 8. 
Result so far: 88.0
Subtract 6472 from 6539 to get 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 809

Step 6:
When dividing 679 by 809, we get 0 with a remainder of 679.
Write down 0 as next digit of the result. 
Result so far: 880.0
Subtract 0 from 679 to get 679.
Take the next digit (4) from the dividend and append it to 679, then repeat: 6794 / 809

Going ahead to step 7:
809 can be fit into 6794 8 times, resulting in a remainder of 322.
Record the quotient 8 as the next digit in the result. 
Result so far: 8808.0
Subtract 6472 from 6794 to get 322.
Take the next digit (7) from the dividend and append it to 322, then repeat: 3227 / 809

Moving on to step 8:
The number 809 fits into 3227 3 times, leaving a remainder of 800.
The next digit of our result is 3. 
Result so far: 88083.0
If we take 2427 away from 3227, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 9:
809 can be fit into 8000 9 times, resulting in a remainder of 719.
Put 9 as the next digit of the answer. 
Result so far: 88083.9
If we take 7281 away from 8000, we end up with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Moving on to step 10:
809 can be fit into 7190 8 times, resulting in a remainder of 718.
Put 8 as the next digit of the answer. 
Result so far: 88083.98
If we subtract 6472 from 7190, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 11:
The number 809 fits into 7180 8 times, leaving a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 88083.988
Subtract 6472 from 7180 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

In conclusion, the division gives 88083.988 with a balance of 0.0708.
