We look at the division of 889456 by 75 
The aim is to understand the frequency of 75 in 889456.

On to step 1:
8 divided by 75 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 75

Advancing to step 2:
If we divide 88 by 75, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 75 away from 88, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 75

Step 3:
The number 75 fits into 139 1 times, leaving a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 75 from 139 to get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 75

Step 4:
If we divide 644 by 75, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 118.0
If we subtract 600 from 644, we get 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 75

Moving on to step 5:
When dividing 445 by 75, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 1185.0
If we take 375 away from 445, we end up with 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 75

Moving on to step 6:
The number 75 fits into 706 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 11859.0
Subtracting 675 from 706 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
75 goes into 310 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 11859.4
Subtracting 300 from 310 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 75, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 11859.41
Deduct 75 from 100 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
The next digit of our result is 3. 
Result so far: 11859.413
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 11859.4133
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 11859.4133, and the remainder is 0.00025.
