Let's divide 409731 by 3
Let's see how many times 3 fits into 409731.

On to step 1:
4 divided by 3 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Advancing to step 2:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 9 from 10 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Let's proceed to step 3:
The number 3 fits into 19 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 18 from 19, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Going ahead to step 4:
When dividing 17 by 3, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 1365.0
The remainder is 2 after subtracting 15 from 17.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Step 5:
3 goes into 23 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 13657.0
Deduct 21 from 23 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

On to step 6:
When dividing 21 by 3, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 136577.0
Deduct 21 from 21 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:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 136577.0
Deduct 0 from 0 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 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 136577.0
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.

In conclusion, the division gives 136577.0 with a balance of 0.0.
