Let's divide 450382 by 3
We're looking to find how many times 3 goes into 450382.

Advancing to step 1:
3 goes into 4 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

On to step 2:
15 divided by 3 is 5 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.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Moving on to step 3:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtract 0 from 0 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

On to step 4:
When dividing 3 by 3, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1501.0
The remainder is 0 after subtracting 3 from 3.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Going ahead to step 5:
If we divide 8 by 3, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 15012.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Step 6:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 150127.0
If we subtract 21 from 22, we 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.

On to step 7:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 150127.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 150127.33
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.

The final outcome is 150127.33, with a leftover of 0.001.
