449409 divided by 3 
Let's see how many times 3 fits into 449409.

Step 1:
4 divided by 3 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Going ahead to step 2:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 12 from 14 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

Advancing to step 3:
If we divide 29 by 3, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 2 after subtracting 27 from 29.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Advancing to step 4:
3 goes into 24 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1498.0
Deduct 24 from 24 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

On to step 5:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14980.0
Subtract 0 from 0 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Let's proceed to step 6:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 149803.0
Subtract 9 from 9 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 149803.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 149803.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 149803.0 and a remainder of 0.0.
