We look at the division of 20384144 by 421 
We're looking to find how many times 421 goes into 20384144.

On to step 1:
2 divided by 421 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 421

On to step 2:
The number 421 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 421

Moving on to step 3:
203 divided by 421 is 0 with a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 203, we get 203.
Include the next digit (8) from the dividend after 203, then repeat: 2038 / 421

Going ahead to step 4:
421 goes into 2038 4 times with a remainder of 354.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1684 from 2038, we get 354.
Include the next digit (4) from the dividend after 354, then repeat: 3544 / 421

Step 5:
The number 421 fits into 3544 8 times, leaving a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 3368 from 3544 and we're left with 176.
Append the next digit (1) from the dividend to 176 and continue with: 1761 / 421

Step 6:
1761 divided by 421 is 4 with a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
If we take 1684 away from 1761, we end up with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 421

Moving on to step 7:
The number 421 fits into 774 1 times, leaving a remainder of 353.
Write down 1 as next digit of the result. 
Result so far: 4841.0
Deduct 421 from 774 and we're left with 353.
Fetch the next digit (4) from the dividend, attach it to 353 and continue: 3534 / 421

Step 8:
421 can be fit into 3534 8 times, resulting in a remainder of 166.
The next digit of our result is 8. 
Result so far: 48418.0
Subtract 3368 from 3534 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 9:
If we divide 1660 by 421, we get 3 and a remainder of 397.
The next digit of our result is 3. 
Result so far: 48418.3
If we take 1263 away from 1660, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 10:
3970 divided by 421 is 9 with a remainder of 181.
The next digit of our result is 9. 
Result so far: 48418.39
Subtracting 3789 from 3970 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 11:
If we divide 1810 by 421, we get 4 and a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 48418.394
Subtract 1684 from 1810 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 12:
421 goes into 1260 2 times with a remainder of 418.
The next digit of our result is 2. 
Result so far: 48418.3942
If we subtract 842 from 1260, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 13:
421 goes into 4180 9 times with a remainder of 391.
The number 9 becomes the next digit in our result. 
Result so far: 48418.39429
Subtract 3789 from 4180 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 14:
3910 divided by 421 is 9 with a remainder of 121.
The next digit of our result is 9. 
Result so far: 48418.394299
If we subtract 3789 from 3910, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The quotient of the division is 48418.394299, and the remainder is 1.21e-05.
