We divide 741439 by 3
Let's see how many times 3 fits into 741439.

On to step 1:
3 goes into 7 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 6 away from 7, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Moving on to step 2:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Advancing to step 3:
21 divided by 3 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
Subtracting 21 from 21 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Step 4:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 2471.0
Subtract 3 from 4 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Advancing to step 5:
13 divided by 3 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 24714.0
Subtracting 12 from 13 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Advancing to step 6:
3 goes into 19 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 247146.0
Subtracting 18 from 19 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 247146.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 247146.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 247146.33 with a remainder of 0.001.
