143394 ÷ 3 
We want to figure out the number of times 143394 can be divided by 3.

Let's proceed to 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
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Going ahead to step 2:
3 goes into 14 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Moving on to step 3:
3 goes into 23 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 21 from 23, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Going ahead to step 4:
23 divided by 3 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
If we subtract 21 from 23, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Going ahead to step 5:
3 can be fit into 29 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 4779.0
The remainder is 2 after subtracting 27 from 29.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Step 6:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 47798.0
Deduct 24 from 24 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.

Step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 47798.0
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.

Step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 47798.0
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.

The final result is 47798.0 with a remainder of 0.0.
