428282 ÷ 3 
Our goal is to divide 428282 by 3.

Step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Going ahead to step 2:
If we divide 12 by 3, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

On to step 3:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Deduct 6 from 8 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Let's proceed to step 4:
If we divide 22 by 3, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1427.0
If we take 21 away from 22, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Moving on to step 5:
If we divide 18 by 3, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 14276.0
Deduct 18 from 18 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Going ahead to step 6:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 142760.0
If we subtract 0 from 2, we 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.

Going ahead to step 7:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 142760.6
If we subtract 18 from 20, we 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:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 142760.66
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.

Our division results in 142760.66 with a remaining 0.002.
