We're dividing 495402 by 3 
Let's see how many times 3 fits into 495402.

Step 1:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Let's proceed to step 2:
19 divided by 3 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 18 from 19, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Let's proceed to step 3:
If we divide 15 by 3, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 165.0
Subtracting 15 from 15 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Going ahead to step 4:
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: 1651.0
If we subtract 3 from 4, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Step 5:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 16513.0
The remainder is 1 after subtracting 9 from 10.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Let's proceed to step 6:
If we divide 12 by 3, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 165134.0
If we subtract 12 from 12, we 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.

Moving on to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 165134.0
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.

Moving on to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 165134.0
Deduct 0 from 0 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.

The final outcome is 165134.0, with a leftover of 0.0.
