We divide 450994 by 3
We want to divide 450994 by 3.

Moving on to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Going ahead to step 2:
When dividing 15 by 3, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 0 after subtracting 15 from 15.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

On to step 3:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 150.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Let's proceed to step 4:
When dividing 9 by 3, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1503.0
If we subtract 9 from 9, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Moving on to step 5:
If we divide 9 by 3, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 15033.0
Subtract 9 from 9 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Step 6:
3 goes into 4 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 150331.0
The remainder is 1 after subtracting 3 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 150331.3
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.

Moving on to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 150331.33
Deduct 9 from 10 and we're left 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.

Our division results in 150331.33 with a remaining 0.001.
