We look at the division of 10815681 by 40 
Our goal is to divide 10815681 by 40.

Moving on to step 1:
When dividing 1 by 40, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 40

Moving on to step 2:
The number 40 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 40

Step 3:
If we divide 108 by 40, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 80 from 108 to get 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 40

Going ahead to step 4:
If we divide 281 by 40, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 1 after subtracting 280 from 281.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 40

Let's proceed to step 5:
If we divide 15 by 40, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 270.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 40

Going ahead to step 6:
The number 40 fits into 156 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 2703.0
Subtracting 120 from 156 leaves us with 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 40

Advancing to step 7:
368 divided by 40 is 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 27039.0
If we take 360 away from 368, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 40

On to step 8:
40 can be fit into 81 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 270392.0
Subtract 80 from 81 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 40, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 270392.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 40, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 270392.02
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
40 goes into 200 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 270392.025
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
40 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 270392.025
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 270392.025
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 270392.025 with a remainder of 0.0.
