We look at the division of 24356415 by 399 
We want to divide 24356415 by 399.

Moving on to step 1:
The number 399 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 399

Moving on to step 2:
399 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 399

Moving on to step 3:
399 can be fit into 243 0 times, resulting in a remainder of 243.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 243 after subtracting 0 from 243.
Take the next digit (5) from the dividend and append it to 243, then repeat: 2435 / 399

Let's proceed to step 4:
When dividing 2435 by 399, we get 6 with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 41 after subtracting 2394 from 2435.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 399

Going ahead to step 5:
If we divide 416 by 399, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtract 399 from 416 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 399

Step 6:
When dividing 174 by 399, we get 0 with a remainder of 174.
The next digit of our result is 0. 
Result so far: 610.0
Subtracting 0 from 174 leaves us with 174.
Grab the next digit (1) from the dividend, add it to 174, then carry on: 1741 / 399

Going ahead to step 7:
The number 399 fits into 1741 4 times, leaving a remainder of 145.
Write down 4 as next digit of the result. 
Result so far: 6104.0
If we subtract 1596 from 1741, we get 145.
Include the next digit (5) from the dividend after 145, then repeat: 1455 / 399

Step 8:
1455 divided by 399 is 3 with a remainder of 258.
The next digit of our result is 3. 
Result so far: 61043.0
Deduct 1197 from 1455 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 9:
The number 399 fits into 2580 6 times, leaving a remainder of 186.
The next digit of our result is 6. 
Result so far: 61043.6
Subtracting 2394 from 2580 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
1860 divided by 399 is 4 with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 61043.64
Subtracting 1596 from 1860 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 11:
399 can be fit into 2640 6 times, resulting in a remainder of 246.
Write down 6 as next digit of the result. 
Result so far: 61043.646
If we subtract 2394 from 2640, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 12:
When dividing 2460 by 399, we get 6 with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 61043.6466
The remainder is 66 after subtracting 2394 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 61043.6466 with a remainder of 0.00066.
