450283 ÷ 3 
We want to figure out the number of times 450283 can be divided by 3.

Going ahead to step 1:
3 goes into 4 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

On to step 2:
3 can be fit into 15 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 15 from 15 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Going ahead to step 3:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 150.0
If we subtract 0 from 0, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Let's proceed to step 4:
3 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Moving on to step 5:
28 divided by 3 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 15009.0
Subtracting 27 from 28 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

On to step 6:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 150094.0
The remainder is 1 after subtracting 12 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 150094.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 150094.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 150094.33 and a remainder of 0.001.
