We look at the division of 964112 by 75 
The aim is to understand the frequency of 75 in 964112.

Advancing to step 1:
The number 75 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 75

Let's proceed to step 2:
75 can be fit into 96 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 21 after subtracting 75 from 96.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 75

Advancing to step 3:
75 goes into 214 2 times with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 150 from 214 and we're left with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 75

Moving on to step 4:
641 divided by 75 is 8 with a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtract 600 from 641 to get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 75

Step 5:
When dividing 411 by 75, we get 5 with a remainder of 36.
The next digit of our result is 5. 
Result so far: 1285.0
Deduct 375 from 411 and we're left with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 75

Step 6:
When dividing 362 by 75, we get 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 12854.0
The remainder is 62 after subtracting 300 from 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
620 divided by 75 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 12854.8
Subtracting 600 from 620 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 75, we get 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 12854.82
Deduct 150 from 200 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 12854.826
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 75 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 12854.8266
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 12854.8266 and a remainder of 0.0005.
