248782 ÷ 75 
The aim is to understand the frequency of 75 in 248782.

Step 1:
75 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 75

Step 2:
If we divide 24 by 75, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 75

Moving on to step 3:
When dividing 248 by 75, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 225 from 248, we get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 75

Advancing to step 4:
75 can be fit into 237 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 225 from 237 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 75

Going ahead to step 5:
75 can be fit into 128 1 times, resulting in a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 331.0
If we take 75 away from 128, we end up with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 75

On to step 6:
532 divided by 75 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3317.0
Deduct 525 from 532 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 75, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 3317.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
75 can be fit into 700 9 times, resulting in a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 3317.09
Deduct 675 from 700 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 9:
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: 3317.093
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.

Advancing to step 10:
75 goes into 250 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 3317.0933
If we take 225 away from 250, we end up 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.

After the division, we end up with 3317.0933 and a remainder of 0.00025.
