Let's divide 3876831 by 449
Our goal is to divide 3876831 by 449.

Step 1:
When dividing 3 by 449, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 449

Moving on to step 2:
449 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 449

Let's proceed to step 3:
449 can be fit into 387 0 times, resulting in a remainder of 387.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 387, we get 387.
Append the next digit (6) from the dividend to 387 and continue with: 3876 / 449

Going ahead to step 4:
When dividing 3876 by 449, we get 8 with a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 3592 from 3876 to get 284.
Bring next digit (8) of the dividend behind the 284 and repeat the process: 2848 / 449

Step 5:
If we divide 2848 by 449, we get 6 and a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 86.0
The remainder is 154 after subtracting 2694 from 2848.
Append the next digit (3) from the dividend to 154 and continue with: 1543 / 449

Let's proceed to step 6:
The number 449 fits into 1543 3 times, leaving a remainder of 196.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
Deduct 1347 from 1543 and we're left with 196.
Take the next digit (1) from the dividend and append it to 196, then repeat: 1961 / 449

Step 7:
If we divide 1961 by 449, we get 4 and a remainder of 165.
Write down 4 as next digit of the result. 
Result so far: 8634.0
Subtracting 1796 from 1961 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 8:
If we divide 1650 by 449, we get 3 and a remainder of 303.
Write down 3 as next digit of the result. 
Result so far: 8634.3
Subtract 1347 from 1650 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 9:
When dividing 3030 by 449, we get 6 with a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 8634.36
If we subtract 2694 from 3030, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
The number 449 fits into 3360 7 times, leaving a remainder of 217.
Write down 7 as next digit of the result. 
Result so far: 8634.367
Subtracting 3143 from 3360 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 11:
449 can be fit into 2170 4 times, resulting in a remainder of 374.
Record the quotient 4 as the next digit in the result. 
Result so far: 8634.3674
Subtracting 1796 from 2170 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 12:
When dividing 3740 by 449, we get 8 with a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 8634.36748
If we subtract 3592 from 3740, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 13:
When dividing 1480 by 449, we get 3 with a remainder of 133.
Write down 3 as next digit of the result. 
Result so far: 8634.367483
If we subtract 1347 from 1480, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 14:
449 can be fit into 1330 2 times, resulting in a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 8634.3674832
Subtracting 898 from 1330 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 15:
449 goes into 4320 9 times with a remainder of 279.
Use 9 as the next digit of our solution. 
Result so far: 8634.36748329
If we subtract 4041 from 4320, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

The final result is 8634.36748329 with a remainder of 2.79e-07.
