We look at the division of 13882797 by 621 
We want to divide 13882797 by 621.

Step 1:
621 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 621

Going ahead to step 2:
The number 621 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 subtract 0 from 13, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 621

Let's proceed to step 3:
The number 621 fits into 138 0 times, leaving a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Include the next digit (8) from the dividend after 138, then repeat: 1388 / 621

Let's proceed to step 4:
If we divide 1388 by 621, we get 2 and a remainder of 146.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1242 from 1388 leaves us with 146.
Fetch the next digit (2) from the dividend, attach it to 146 and continue: 1462 / 621

On to step 5:
621 goes into 1462 2 times with a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 1242 from 1462, we get 220.
Fetch the next digit (7) from the dividend, attach it to 220 and continue: 2207 / 621

Going ahead to step 6:
If we divide 2207 by 621, we get 3 and a remainder of 344.
Put 3 as the next digit of the answer. 
Result so far: 223.0
Subtract 1863 from 2207 to get 344.
Append the next digit (9) from the dividend to 344 and continue with: 3449 / 621

On to step 7:
The number 621 fits into 3449 5 times, leaving a remainder of 344.
Write down 5 as next digit of the result. 
Result so far: 2235.0
Subtract 3105 from 3449 to get 344.
Take the next digit (7) from the dividend and append it to 344, then repeat: 3447 / 621

Moving on to step 8:
The number 621 fits into 3447 5 times, leaving a remainder of 342.
Put 5 as the next digit of the answer. 
Result so far: 22355.0
If we take 3105 away from 3447, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 9:
3420 divided by 621 is 5 with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 22355.5
Subtracting 3105 from 3420 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 10:
621 can be fit into 3150 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 22355.55
Subtract 3105 from 3150 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 22355.55, and the remainder is 0.045.
