13385049 ÷ 624 
Our goal is to divide 13385049 by 624.

Advancing to step 1:
If we divide 1 by 624, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 624

Step 2:
The number 624 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 624

Moving on to step 3:
The number 624 fits into 133 0 times, leaving a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 133, we get 133.
Append the next digit (8) from the dividend to 133 and continue with: 1338 / 624

Going ahead to step 4:
The number 624 fits into 1338 2 times, leaving a remainder of 90.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1248 from 1338, we get 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 624

Advancing to step 5:
If we divide 905 by 624, we get 1 and a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 624 away from 905, we end up with 281.
Take the next digit (0) from the dividend and append it to 281, then repeat: 2810 / 624

On to step 6:
624 goes into 2810 4 times with a remainder of 314.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
Subtract 2496 from 2810 to get 314.
Include the next digit (4) from the dividend after 314, then repeat: 3144 / 624

Advancing to step 7:
3144 divided by 624 is 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 2145.0
If we subtract 3120 from 3144, we get 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 624

Advancing to step 8:
249 divided by 624 is 0 with a remainder of 249.
Write down 0 as next digit of the result. 
Result so far: 21450.0
Deduct 0 from 249 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 9:
2490 divided by 624 is 3 with a remainder of 618.
Write down 3 as next digit of the result. 
Result so far: 21450.3
The remainder is 618 after subtracting 1872 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 10:
624 can be fit into 6180 9 times, resulting in a remainder of 564.
Write down 9 as next digit of the result. 
Result so far: 21450.39
Deduct 5616 from 6180 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 11:
If we divide 5640 by 624, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 21450.399
If we take 5616 away from 5640, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 21450.399 with a remainder of 0.0024.
