We're dividing 259243 by 75 
The aim is to understand the frequency of 75 in 259243.

Moving on to step 1:
The number 75 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 75

Going ahead to step 2:
75 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 75

Moving on to step 3:
75 goes into 259 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 225 away from 259, we end up with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 75

Step 4:
When dividing 342 by 75, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 300 from 342 and we're left with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 75

Step 5:
The number 75 fits into 424 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 345.0
If we take 375 away from 424, we end up with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 75

Advancing to step 6:
493 divided by 75 is 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 3456.0
The remainder is 43 after subtracting 450 from 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
430 divided by 75 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 3456.5
The remainder is 55 after subtracting 375 from 430.
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: 3456.57
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.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 3456.573
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.

Advancing to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 3456.5733
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.

In conclusion, the division gives 3456.5733 with a balance of 0.00025.
