We divide 142673 by 3
Let's see how many times 3 fits into 142673.

Going ahead to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Step 2:
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: 4.0
Subtracting 12 from 14 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

On to step 3:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 21 away from 22, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

Moving on to step 4:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 475.0
Deduct 15 from 16 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Let's proceed to step 5:
The number 3 fits into 17 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 4755.0
If we take 15 away from 17, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Let's proceed to step 6:
When dividing 23 by 3, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 47557.0
Deduct 21 from 23 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.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 47557.6
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.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 47557.66
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 47557.66 with a remaining 0.002.
