74409 ÷ 75 
The aim is to understand the frequency of 75 in 74409.

Step 1:
75 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 75

Advancing to step 2:
75 goes into 74 0 times with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 75

Let's proceed to step 3:
744 divided by 75 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 675 away from 744, we end up with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 75

Let's proceed to step 4:
If we divide 690 by 75, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 675 away from 690, we end up with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 75

Let's proceed to step 5:
If we divide 159 by 75, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 992.0
Subtract 150 from 159 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
The number 75 fits into 90 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 992.1
If we subtract 75 from 90, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 75 fits into 150 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 992.12
If we subtract 150 from 150, 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.

Moving on to step 8:
When dividing 0 by 75, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 992.12
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.

On to step 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 992.12
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.

After the division, we end up with 992.12 and a remainder of 0.0.
