974289 ÷ 3 
The aim is to understand the frequency of 3 in 974289.

Let's proceed to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

On to step 2:
7 divided by 3 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 1 after subtracting 6 from 7.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Moving on to step 3:
When dividing 14 by 3, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 324.0
Subtracting 12 from 14 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Going ahead to step 4:
22 divided by 3 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3247.0
If we take 21 away from 22, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Going ahead to step 5:
18 divided by 3 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 32476.0
Subtract 18 from 18 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Step 6:
9 divided by 3 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 324763.0
Deduct 9 from 9 and we're left 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.

Let's proceed to step 7:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 324763.0
The remainder is 0 after subtracting 0 from 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 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 324763.0
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.

Our division results in 324763.0 with a remaining 0.0.
