We're dividing 290487 by 74 
The aim is to understand the frequency of 74 in 290487.

On to step 1:
If we divide 2 by 74, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 74

Going ahead to step 2:
When dividing 29 by 74, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 74

Step 3:
74 can be fit into 290 3 times, resulting in a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 222 away from 290, we end up with 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 74

On to step 4:
74 goes into 684 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 666 from 684 to get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 74

Going ahead to step 5:
74 can be fit into 188 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 392.0
The remainder is 40 after subtracting 148 from 188.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 74

Step 6:
74 goes into 407 5 times with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 3925.0
If we take 370 away from 407, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
370 divided by 74 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3925.5
Subtracting 370 from 370 leaves us 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 8:
74 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3925.5
If we take 0 away from 0, we end up 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.

Moving on to step 9:
When dividing 0 by 74, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3925.5
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 3925.5 with a remainder of 0.0.
