We look at the division of 54629487 by 449 
Let's see how many times 449 fits into 54629487.

Going ahead to step 1:
If we divide 5 by 449, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 449

On to step 2:
The number 449 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 449

Going ahead to step 3:
The number 449 fits into 546 1 times, leaving a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 449 from 546 and we're left with 97.
Bring next digit (2) of the dividend behind the 97 and repeat the process: 972 / 449

Going ahead to step 4:
449 goes into 972 2 times with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 898 from 972 and we're left with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 449

Advancing to step 5:
If we divide 749 by 449, we get 1 and a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we take 449 away from 749, we end up with 300.
Take the next digit (4) from the dividend and append it to 300, then repeat: 3004 / 449

Step 6:
3004 divided by 449 is 6 with a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 1216.0
If we subtract 2694 from 3004, we get 310.
Bring next digit (8) of the dividend behind the 310 and repeat the process: 3108 / 449

On to step 7:
449 can be fit into 3108 6 times, resulting in a remainder of 414.
The next digit of our result is 6. 
Result so far: 12166.0
If we subtract 2694 from 3108, we get 414.
Grab the next digit (7) from the dividend, add it to 414, then carry on: 4147 / 449

Moving on to step 8:
When dividing 4147 by 449, we get 9 with a remainder of 106.
Write down 9 as next digit of the result. 
Result so far: 121669.0
Deduct 4041 from 4147 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
449 can be fit into 1060 2 times, resulting in a remainder of 162.
The next digit of our result is 2. 
Result so far: 121669.2
Subtract 898 from 1060 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
449 can be fit into 1620 3 times, resulting in a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 121669.23
If we subtract 1347 from 1620, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 11:
449 goes into 2730 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 121669.236
The remainder is 36 after subtracting 2694 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
360 divided by 449 is 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 121669.236
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
3600 divided by 449 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 121669.23608
If we take 3592 away from 3600, 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.

Going ahead to step 14:
The number 449 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 121669.23608
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
800 divided by 449 is 1 with a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 121669.2360801
The remainder is 351 after subtracting 449 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 16:
When dividing 3510 by 449, we get 7 with a remainder of 367.
The next digit of our result is 7. 
Result so far: 121669.23608017
Subtract 3143 from 3510 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

In conclusion, the division gives 121669.23608017 with a balance of 3.67e-07.
