We're dividing 81440 by 18 
We're looking to find how many times 18 goes into 81440.

On to step 1:
18 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 18

Advancing to step 2:
18 goes into 81 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 72 from 81 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 18

Step 3:
If we divide 94 by 18, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 90 from 94 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 18

Let's proceed to step 4:
If we divide 44 by 18, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 452.0
Subtract 36 from 44 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 18

Going ahead to step 5:
18 goes into 80 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4524.0
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 6:
When dividing 80 by 18, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4524.4
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 18, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4524.44
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 4524.44 with a remainder of 0.008.
