890425 divided by 3 
The aim is to understand the frequency of 3 in 890425.

Moving on to step 1:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

On to step 2:
If we divide 29 by 3, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 27 from 29 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Let's proceed to step 3:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 296.0
Deduct 18 from 20 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Moving on to step 4:
24 divided by 3 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2968.0
If we take 24 away from 24, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Advancing to step 5:
2 divided by 3 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 29680.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Let's proceed to step 6:
3 can be fit into 25 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 296808.0
If we subtract 24 from 25, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 296808.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 296808.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 296808.33 and a remainder of 0.001.
