We divide 454518 by 3
Our goal is to divide 454518 by 3.

On to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

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
Deduct 15 from 15 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

On to step 3:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 151.0
The remainder is 1 after subtracting 3 from 4.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Step 4:
3 goes into 15 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1515.0
The remainder is 0 after subtracting 15 from 15.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Going ahead to step 5:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 15150.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Moving on to step 6:
18 divided by 3 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 151506.0
Deduct 18 from 18 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.

Moving on to step 7:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 151506.0
Subtracting 0 from 0 leaves us 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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 151506.0
Subtract 0 from 0 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.

In conclusion, the division gives 151506.0 with a balance of 0.0.
