669402 ÷ 24 
The aim is to understand the frequency of 24 in 669402.

Step 1:
6 divided by 24 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 24

On to step 2:
66 divided by 24 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 48 from 66 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 24

Step 3:
If we divide 189 by 24, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 27.0
If we take 168 away from 189, we end up with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 24

Moving on to step 4:
214 divided by 24 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 278.0
Deduct 192 from 214 and we're left with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 24

Step 5:
24 can be fit into 220 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 2789.0
If we take 216 away from 220, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 24

Let's proceed to step 6:
When dividing 42 by 24, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 27891.0
If we take 24 away from 42, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 24, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 27891.7
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 24 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 27891.75
Subtract 120 from 120 to 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.

Moving on to step 9:
0 divided by 24 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27891.75
Deduct 0 from 0 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.

Going ahead to step 10:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27891.75
Subtract 0 from 0 to 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.

The final result is 27891.75 with a remainder of 0.0.
