428654 divided by 3 
The aim is to understand the frequency of 3 in 428654.

Moving on to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 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
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Let's proceed to step 3:
When dividing 8 by 3, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 142.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Moving on to step 4:
3 goes into 26 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1428.0
Subtracting 24 from 26 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Moving on to step 5:
3 can be fit into 25 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 14288.0
Subtracting 24 from 25 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Going ahead to step 6:
3 goes into 14 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 142884.0
If we take 12 away from 14, 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.

On to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 142884.6
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.

Moving on to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 142884.66
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.

After the division, we end up with 142884.66 and a remainder of 0.002.
