81252079 ÷ 814 
We want to divide 81252079 by 814.

Let's proceed to step 1:
When dividing 8 by 814, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 814

Let's proceed to step 2:
814 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 814

Let's proceed to step 3:
When dividing 812 by 814, we get 0 with a remainder of 812.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 812, we end up with 812.
Fetch the next digit (5) from the dividend, attach it to 812 and continue: 8125 / 814

Moving on to step 4:
The number 814 fits into 8125 9 times, leaving a remainder of 799.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7326 from 8125 leaves us with 799.
Take the next digit (2) from the dividend and append it to 799, then repeat: 7992 / 814

On to step 5:
The number 814 fits into 7992 9 times, leaving a remainder of 666.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 7326 away from 7992, we end up with 666.
Append the next digit (0) from the dividend to 666 and continue with: 6660 / 814

Step 6:
814 can be fit into 6660 8 times, resulting in a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 998.0
Subtracting 6512 from 6660 leaves us with 148.
Bring next digit (7) of the dividend behind the 148 and repeat the process: 1487 / 814

Step 7:
If we divide 1487 by 814, we get 1 and a remainder of 673.
Use 1 as the next digit of our solution. 
Result so far: 9981.0
The remainder is 673 after subtracting 814 from 1487.
Fetch the next digit (9) from the dividend, attach it to 673 and continue: 6739 / 814

Let's proceed to step 8:
When dividing 6739 by 814, we get 8 with a remainder of 227.
Record the quotient 8 as the next digit in the result. 
Result so far: 99818.0
If we take 6512 away from 6739, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 9:
2270 divided by 814 is 2 with a remainder of 642.
The next digit of our result is 2. 
Result so far: 99818.2
Subtracting 1628 from 2270 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Step 10:
6420 divided by 814 is 7 with a remainder of 722.
Put 7 as the next digit of the answer. 
Result so far: 99818.27
If we take 5698 away from 6420, we end up with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 11:
When dividing 7220 by 814, we get 8 with a remainder of 708.
Put 8 as the next digit of the answer. 
Result so far: 99818.278
Subtracting 6512 from 7220 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Going ahead to step 12:
If we divide 7080 by 814, we get 8 and a remainder of 568.
Put 8 as the next digit of the answer. 
Result so far: 99818.2788
If we subtract 6512 from 7080, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final outcome is 99818.2788, with a leftover of 0.00568.
