We look at the division of 428687 by 3 
We want to figure out the number of times 428687 can be divided by 3.

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
Subtracting 3 from 4 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 3

Step 2:
The number 3 fits into 12 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 0 after subtracting 12 from 12.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Advancing to step 4:
3 can be fit into 26 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1428.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Moving on to step 5:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 14289.0
If we subtract 27 from 28, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Step 6:
3 can be fit into 17 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 142895.0
Subtracting 15 from 17 leaves us 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.

Step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 142895.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 142895.66
If we take 18 away from 20, we end up 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 142895.66 with a remaining 0.002.
