We look at the division of 142046 by 3 
We're looking to find how many times 3 goes into 142046.

Step 1:
1 divided by 3 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Let's proceed to step 2:
14 divided by 3 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 2 after subtracting 12 from 14.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Step 3:
3 goes into 22 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 21 from 22 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

On to step 4:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 473.0
If we subtract 9 from 10, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Let's proceed to step 5:
14 divided by 3 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4734.0
Subtracting 12 from 14 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Let's proceed to step 6:
3 can be fit into 26 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 47348.0
The remainder is 2 after subtracting 24 from 26.
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:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 47348.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 47348.66
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.

After the division, we end up with 47348.66 and a remainder of 0.002.
