We're dividing 81254277 by 815 
Let's see how many times 815 fits into 81254277.

Let's proceed to step 1:
The number 815 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 815

On to step 2:
If we divide 81 by 815, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 815

Moving on to step 3:
The number 815 fits into 812 0 times, leaving a remainder of 812.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 812, we get 812.
Bring next digit (5) of the dividend behind the 812 and repeat the process: 8125 / 815

On to step 4:
815 goes into 8125 9 times with a remainder of 790.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 790 after subtracting 7335 from 8125.
Bring next digit (4) of the dividend behind the 790 and repeat the process: 7904 / 815

On to step 5:
When dividing 7904 by 815, we get 9 with a remainder of 569.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 569 after subtracting 7335 from 7904.
Bring next digit (2) of the dividend behind the 569 and repeat the process: 5692 / 815

Let's proceed to step 6:
815 can be fit into 5692 6 times, resulting in a remainder of 802.
Write down 6 as next digit of the result. 
Result so far: 996.0
Deduct 4890 from 5692 and we're left with 802.
Fetch the next digit (7) from the dividend, attach it to 802 and continue: 8027 / 815

Moving on to step 7:
8027 divided by 815 is 9 with a remainder of 692.
The number 9 becomes the next digit in our result. 
Result so far: 9969.0
The remainder is 692 after subtracting 7335 from 8027.
Bring next digit (7) of the dividend behind the 692 and repeat the process: 6927 / 815

Moving on to step 8:
815 goes into 6927 8 times with a remainder of 407.
Write down 8 as next digit of the result. 
Result so far: 99698.0
Subtracting 6520 from 6927 leaves us with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Let's proceed to step 9:
When dividing 4070 by 815, we get 4 with a remainder of 810.
The next digit of our result is 4. 
Result so far: 99698.4
If we subtract 3260 from 4070, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 10:
If we divide 8100 by 815, we get 9 and a remainder of 765.
Put 9 as the next digit of the answer. 
Result so far: 99698.49
If we subtract 7335 from 8100, we get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Step 11:
When dividing 7650 by 815, we get 9 with a remainder of 315.
Write down 9 as next digit of the result. 
Result so far: 99698.499
If we take 7335 away from 7650, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Our division results in 99698.499 with a remaining 0.0315.
