We look at the division of 450002 by 3 
We're looking to find how many times 3 goes into 450002.

Moving on to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Let's proceed to step 2:
3 goes into 15 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 15 from 15, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Advancing to step 3:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we take 0 away from 0, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Advancing to step 4:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1500.0
If we take 0 away from 0, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Let's proceed to step 5:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 15000.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Going ahead to step 6:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 150000.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 150000.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 150000.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 150000.66, with a leftover of 0.002.
