We divide 476946 by 3
We're looking to find how many times 3 goes into 476946.

Going ahead to step 1:
3 goes into 4 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Let's proceed to step 2:
The number 3 fits into 17 5 times, leaving a remainder of 2.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 15 from 17 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

On to step 3:
3 goes into 26 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Deduct 24 from 26 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Moving on to step 4:
3 goes into 29 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1589.0
Subtract 27 from 29 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Step 5:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 15898.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Going ahead to step 6:
3 goes into 6 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 158982.0
Subtract 6 from 6 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.

On to step 7:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 158982.0
If we subtract 0 from 0, 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.

Step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 158982.0
If we subtract 0 from 0, 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.

The final result is 158982.0 with a remainder of 0.0.
