89868818 ÷ 815 
Let's see how many times 815 fits into 89868818.

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
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 815

Moving on to step 2:
The number 815 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (8) from the dividend to 89 and continue with: 898 / 815

Going ahead to step 3:
815 goes into 898 1 times with a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 815 from 898 and we're left with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 815

Moving on to step 4:
If we divide 836 by 815, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 815 away from 836, we end up with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 815

Going ahead to step 5:
If we divide 218 by 815, we get 0 and a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 218 to get 218.
Include the next digit (8) from the dividend after 218, then repeat: 2188 / 815

Let's proceed to step 6:
The number 815 fits into 2188 2 times, leaving a remainder of 558.
Use 2 as the next digit of our solution. 
Result so far: 1102.0
If we take 1630 away from 2188, we end up with 558.
Fetch the next digit (1) from the dividend, attach it to 558 and continue: 5581 / 815

Step 7:
When dividing 5581 by 815, we get 6 with a remainder of 691.
The next digit of our result is 6. 
Result so far: 11026.0
If we take 4890 away from 5581, we end up with 691.
Fetch the next digit (8) from the dividend, attach it to 691 and continue: 6918 / 815

On to step 8:
6918 divided by 815 is 8 with a remainder of 398.
The number 8 becomes the next digit in our result. 
Result so far: 110268.0
Subtracting 6520 from 6918 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 9:
3980 divided by 815 is 4 with a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 110268.4
If we subtract 3260 from 3980, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
7200 divided by 815 is 8 with a remainder of 680.
The next digit of our result is 8. 
Result so far: 110268.48
If we subtract 6520 from 7200, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 11:
If we divide 6800 by 815, we get 8 and a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 110268.488
Subtracting 6520 from 6800 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 110268.488, with a leftover of 0.028.
