We look at the division of 43946 by 18 
Our goal is to divide 43946 by 18.

Step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 18

On to step 2:
The number 18 fits into 43 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 36 from 43 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 18

On to step 3:
When dividing 79 by 18, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 7 after subtracting 72 from 79.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 18

Going ahead to step 4:
The number 18 fits into 74 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Deduct 72 from 74 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 18

Step 5:
18 can be fit into 26 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 2441.0
Subtract 18 from 26 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.

Going ahead to step 6:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 2441.4
If we subtract 72 from 80, we 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.

Going ahead to step 7:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2441.44
If we subtract 72 from 80, we 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.

The final result is 2441.44 with a remainder of 0.008.
