248608 divided by 75 
The aim is to understand the frequency of 75 in 248608.

On to step 1:
2 divided by 75 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 75

Step 2:
The number 75 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 75

Step 3:
When dividing 248 by 75, we get 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 225 from 248 leaves us with 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 75

Step 4:
If we divide 236 by 75, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 225 from 236 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 75

Step 5:
The number 75 fits into 110 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 331.0
Deduct 75 from 110 and we're left with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 75

On to step 6:
75 can be fit into 358 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 3314.0
Subtracting 300 from 358 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
580 divided by 75 is 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 3314.7
If we take 525 away from 580, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
If we divide 550 by 75, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 3314.77
Subtracting 525 from 550 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 final result is 3314.77 with a remainder of 0.025.
