We look at the division of 20383187 by 449 
Let's see how many times 449 fits into 20383187.

Let's proceed to step 1:
If we divide 2 by 449, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 449

Going ahead to step 2:
449 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 449

Let's proceed to step 3:
203 divided by 449 is 0 with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Append the next digit (8) from the dividend to 203 and continue with: 2038 / 449

Going ahead to step 4:
When dividing 2038 by 449, we get 4 with a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1796 from 2038, we get 242.
Grab the next digit (3) from the dividend, add it to 242, then carry on: 2423 / 449

Moving on to step 5:
If we divide 2423 by 449, we get 5 and a remainder of 178.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 2245 away from 2423, we end up with 178.
Take the next digit (1) from the dividend and append it to 178, then repeat: 1781 / 449

Let's proceed to step 6:
449 goes into 1781 3 times with a remainder of 434.
Use 3 as the next digit of our solution. 
Result so far: 453.0
Deduct 1347 from 1781 and we're left with 434.
Take the next digit (8) from the dividend and append it to 434, then repeat: 4348 / 449

Step 7:
4348 divided by 449 is 9 with a remainder of 307.
Record the quotient 9 as the next digit in the result. 
Result so far: 4539.0
The remainder is 307 after subtracting 4041 from 4348.
Fetch the next digit (7) from the dividend, attach it to 307 and continue: 3077 / 449

Moving on to step 8:
3077 divided by 449 is 6 with a remainder of 383.
Put 6 as the next digit of the answer. 
Result so far: 45396.0
Deduct 2694 from 3077 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 9:
The number 449 fits into 3830 8 times, leaving a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 45396.8
Subtract 3592 from 3830 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 10:
The number 449 fits into 2380 5 times, leaving a remainder of 135.
The next digit of our result is 5. 
Result so far: 45396.85
If we take 2245 away from 2380, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
449 goes into 1350 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 45396.853
Deduct 1347 from 1350 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
449 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 45396.853
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
449 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 45396.853
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 45396.853, with a leftover of 0.0003.
