Let's divide 21834878 by 449
Let's see how many times 449 fits into 21834878.

Going ahead to step 1:
The number 449 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 449

Let's proceed to step 2:
449 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 449

Let's proceed to step 3:
When dividing 218 by 449, we get 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Append the next digit (3) from the dividend to 218 and continue with: 2183 / 449

Step 4:
2183 divided by 449 is 4 with a remainder of 387.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 387 after subtracting 1796 from 2183.
Bring next digit (4) of the dividend behind the 387 and repeat the process: 3874 / 449

Step 5:
When dividing 3874 by 449, we get 8 with a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 3592 from 3874 and we're left with 282.
Fetch the next digit (8) from the dividend, attach it to 282 and continue: 2828 / 449

On to step 6:
If we divide 2828 by 449, we get 6 and a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 486.0
The remainder is 134 after subtracting 2694 from 2828.
Grab the next digit (7) from the dividend, add it to 134, then carry on: 1347 / 449

On to step 7:
449 goes into 1347 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 4863.0
If we take 1347 away from 1347, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 449

Let's proceed to step 8:
449 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 48630.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 449 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 48630.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
The number 449 fits into 800 1 times, leaving a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 48630.01
Subtracting 449 from 800 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 11:
3510 divided by 449 is 7 with a remainder of 367.
Write down 7 as next digit of the result. 
Result so far: 48630.017
Deduct 3143 from 3510 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 12:
The number 449 fits into 3670 8 times, leaving a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 48630.0178
Deduct 3592 from 3670 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
When dividing 780 by 449, we get 1 with a remainder of 331.
Use 1 as the next digit of our solution. 
Result so far: 48630.01781
If we take 449 away from 780, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 14:
449 can be fit into 3310 7 times, resulting in a remainder of 167.
Record the quotient 7 as the next digit in the result. 
Result so far: 48630.017817
Deduct 3143 from 3310 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 15:
1670 divided by 449 is 3 with a remainder of 323.
Write down 3 as next digit of the result. 
Result so far: 48630.0178173
The remainder is 323 after subtracting 1347 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 16:
When dividing 3230 by 449, we get 7 with a remainder of 87.
The next digit of our result is 7. 
Result so far: 48630.01781737
If we subtract 3143 from 3230, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 48630.01781737 and a remainder of 8.7e-08.
