We look at the division of 394469 by 3 
Let's see how many times 3 fits into 394469.

Going ahead to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Moving on to step 2:
3 goes into 9 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

On to step 3:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtract 3 from 4 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Let's proceed to step 4:
3 can be fit into 14 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1314.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Let's proceed to step 5:
When dividing 26 by 3, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13148.0
Subtract 24 from 26 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

On to step 6:
If we divide 29 by 3, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 131489.0
Subtracting 27 from 29 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.

Step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 131489.6
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.

Moving on to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 131489.66
Subtracting 18 from 20 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.

Our division results in 131489.66 with a remaining 0.002.
