42480938 divided by 449 
Our goal is to divide 42480938 by 449.

Advancing to step 1:
449 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 449

On to step 2:
449 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 449

Let's proceed to step 3:
449 goes into 424 0 times with a remainder of 424.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 424 to get 424.
Grab the next digit (8) from the dividend, add it to 424, then carry on: 4248 / 449

On to step 4:
If we divide 4248 by 449, we get 9 and a remainder of 207.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 207 after subtracting 4041 from 4248.
Grab the next digit (0) from the dividend, add it to 207, then carry on: 2070 / 449

Step 5:
2070 divided by 449 is 4 with a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 274 after subtracting 1796 from 2070.
Include the next digit (9) from the dividend after 274, then repeat: 2749 / 449

On to step 6:
2749 divided by 449 is 6 with a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 946.0
The remainder is 55 after subtracting 2694 from 2749.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 449

Let's proceed to step 7:
When dividing 553 by 449, we get 1 with a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 9461.0
If we take 449 away from 553, we end up with 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 449

Moving on to step 8:
449 goes into 1048 2 times with a remainder of 150.
Put 2 as the next digit of the answer. 
Result so far: 94612.0
Subtracting 898 from 1048 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
449 can be fit into 1500 3 times, resulting in a remainder of 153.
The next digit of our result is 3. 
Result so far: 94612.3
The remainder is 153 after subtracting 1347 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 10:
When dividing 1530 by 449, we get 3 with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 94612.33
If we take 1347 away from 1530, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

After the division, we end up with 94612.33 and a remainder of 0.183.
