We're dividing 78244 by 75 
The aim is to understand the frequency of 75 in 78244.

Let's proceed to step 1:
7 divided by 75 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 75

Advancing to step 2:
If we divide 78 by 75, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 75 away from 78, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 75

Step 3:
If we divide 32 by 75, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 75

Going ahead to step 4:
If we divide 324 by 75, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 300 from 324 and we're left with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 75

Going ahead to step 5:
When dividing 244 by 75, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 1043.0
If we take 225 away from 244, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 6:
When dividing 190 by 75, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 1043.2
Subtract 150 from 190 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
75 goes into 400 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1043.25
Deduct 375 from 400 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.

Let's proceed to step 8:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1043.253
Subtract 225 from 250 to 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.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 1043.2533
The remainder is 25 after subtracting 225 from 250.
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 1043.2533, and the remainder is 0.00025.
