We're dividing 478511 by 3 
Let's see how many times 3 fits into 478511.

Moving on to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

Let's proceed to step 2:
17 divided by 3 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 15 from 17 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Step 3:
If we divide 28 by 3, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we subtract 27 from 28, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Going ahead to step 4:
If we divide 15 by 3, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1595.0
If we take 15 away from 15, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

Advancing to step 5:
When dividing 1 by 3, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 15950.0
If we subtract 0 from 1, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Going ahead to step 6:
When dividing 11 by 3, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 159503.0
If we take 9 away from 11, we end up 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.

Step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 159503.6
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.

Advancing to step 8:
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: 159503.66
If we take 18 away from 20, we end up 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 quotient of the division is 159503.66, and the remainder is 0.002.
