We divide 480146 by 3
We're looking to find how many times 3 goes into 480146.

Let's proceed to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Moving on to step 2:
When dividing 18 by 3, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 18 from 18 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Let's proceed to step 3:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we take 0 away from 0, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Step 4:
3 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1600.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Step 5:
14 divided by 3 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 16004.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Moving on to step 6:
When dividing 26 by 3, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 160048.0
Subtracting 24 from 26 leaves us 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.

Moving on to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 160048.6
If we subtract 18 from 20, we 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.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 160048.66
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.

The final result is 160048.66 with a remainder of 0.002.
