We divide 432420 by 3
We want to divide 432420 by 3.

Moving on to step 1:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Going ahead to step 2:
3 goes into 13 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 12 from 13 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Going ahead to step 3:
The number 3 fits into 12 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we subtract 12 from 12, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Let's proceed to step 4:
3 goes into 4 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1441.0
The remainder is 1 after subtracting 3 from 4.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Moving on to step 5:
If we divide 12 by 3, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 14414.0
Deduct 12 from 12 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Let's proceed to step 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 144140.0
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.

Going ahead to step 7:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 144140.0
If we subtract 0 from 0, we 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.

Moving on to step 8:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 144140.0
If we subtract 0 from 0, we 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 outcome is 144140.0, with a leftover of 0.0.
