We're dividing 396543 by 24 
We want to divide 396543 by 24.

Let's proceed to step 1:
When dividing 3 by 24, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 24

Step 2:
24 goes into 39 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 24 away from 39, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 24

On to step 3:
The number 24 fits into 156 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 144 from 156 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 24

On to step 4:
When dividing 125 by 24, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 165.0
The remainder is 5 after subtracting 120 from 125.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 24

Moving on to step 5:
If we divide 54 by 24, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1652.0
If we subtract 48 from 54, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 24

Let's proceed to step 6:
When dividing 63 by 24, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 16522.0
If we subtract 48 from 63, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 24 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 16522.6
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 24, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 16522.62
Deduct 48 from 60 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 24, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 16522.625
If we take 120 away from 120, we end up with 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 10:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16522.625
Subtract 0 from 0 to 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.

Let's proceed to step 11:
0 divided by 24 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16522.625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 16522.625 with a remaining 0.0.
