We're dividing 81751 by 18 
Our goal is to divide 81751 by 18.

Let's proceed to step 1:
When dividing 8 by 18, we get 0 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.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 18

Step 2:
If we divide 81 by 18, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 72 from 81 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 18

Step 3:
18 goes into 97 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 90 from 97 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 18

On to step 4:
When dividing 75 by 18, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 454.0
Subtracting 72 from 75 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 18

On to step 5:
When dividing 31 by 18, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 4541.0
Subtracting 18 from 31 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 6:
If we divide 130 by 18, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 4541.7
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 18, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 4541.72
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 4541.722
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 4541.722 with a remainder of 0.0004.
