Let's divide 81104137 by 215
Our goal is to divide 81104137 by 215.

Step 1:
When dividing 8 by 215, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 215

Moving on to step 2:
215 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 215

Let's proceed to step 3:
215 goes into 811 3 times with a remainder of 166.
The next digit of our result is 3. 
Result so far: 3.0
If we take 645 away from 811, we end up with 166.
Grab the next digit (0) from the dividend, add it to 166, then carry on: 1660 / 215

Let's proceed to step 4:
When dividing 1660 by 215, we get 7 with a remainder of 155.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 1505 from 1660 to get 155.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 215

Advancing to step 5:
The number 215 fits into 1554 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 377.0
If we subtract 1505 from 1554, we get 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 215

Going ahead to step 6:
When dividing 491 by 215, we get 2 with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 3772.0
Deduct 430 from 491 and we're left with 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 215

Going ahead to step 7:
215 can be fit into 613 2 times, resulting in a remainder of 183.
Record the quotient 2 as the next digit in the result. 
Result so far: 37722.0
The remainder is 183 after subtracting 430 from 613.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 215

Moving on to step 8:
The number 215 fits into 1837 8 times, leaving a remainder of 117.
Record the quotient 8 as the next digit in the result. 
Result so far: 377228.0
If we take 1720 away from 1837, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
If we divide 1170 by 215, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 377228.5
The remainder is 95 after subtracting 1075 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
215 goes into 950 4 times with a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 377228.54
If we subtract 860 from 950, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
215 can be fit into 900 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 377228.544
If we take 860 away from 900, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 377228.544 with a remainder of 0.004.
