We're dividing 726434 by 3 
Let's see how many times 3 fits into 726434.

Let's proceed to step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 6 away from 7, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Moving on to step 2:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 12 from 12 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

On to step 3:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 242.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Advancing to step 4:
3 goes into 4 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 2421.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Step 5:
3 goes into 13 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 24214.0
Deduct 12 from 13 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

On to step 6:
If we divide 14 by 3, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 242144.0
Deduct 12 from 14 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.

Step 7:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 242144.6
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.

Advancing to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 242144.66
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 242144.66 and a remainder of 0.002.
