We look at the division of 478149 by 3 
We want to figure out the number of times 478149 can be divided by 3.

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
Subtract 3 from 4 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

Let's proceed to step 2:
3 can be fit into 17 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 15.0
If we take 15 away from 17, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Going ahead to step 3:
If we divide 28 by 3, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 159.0
If we take 27 away from 28, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Step 4:
When dividing 11 by 3, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1593.0
Deduct 9 from 11 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Step 5:
3 can be fit into 24 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 15938.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

On to step 6:
When dividing 9 by 3, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 159383.0
Deduct 9 from 9 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.

Let's proceed to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 159383.0
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:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 159383.0
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.

After the division, we end up with 159383.0 and a remainder of 0.0.
