We look at the division of 428820 by 3 
Let's see how many times 3 fits into 428820.

Moving on to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Step 2:
3 can be fit into 12 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 12 from 12 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Moving on to step 3:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 6 from 8, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Let's proceed to step 4:
3 goes into 28 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1429.0
If we take 27 away from 28, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Advancing to step 5:
3 can be fit into 12 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 14294.0
If we subtract 12 from 12, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Step 6:
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: 142940.0
If we take 0 away from 0, we end up 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.

Going ahead to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 142940.0
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.

On to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 142940.0
If we take 0 away from 0, we end up 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.

Our division results in 142940.0 with a remaining 0.0.
