432689 divided by 3 
Our goal is to divide 432689 by 3.

Let's proceed to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

On to step 2:
13 divided by 3 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Step 3:
When dividing 12 by 3, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 144.0
Subtract 12 from 12 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Let's proceed to step 4:
3 goes into 6 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 1442.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

On to step 5:
When dividing 8 by 3, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 14422.0
Deduct 6 from 8 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

Advancing to step 6:
When dividing 29 by 3, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 144229.0
Deduct 27 from 29 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.

Moving on to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 144229.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 144229.66
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.

The final outcome is 144229.66, with a leftover of 0.002.
