251882 ÷ 75 
The aim is to understand the frequency of 75 in 251882.

Advancing to step 1:
When dividing 2 by 75, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 75

Moving on to step 2:
If we divide 25 by 75, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 75

Let's proceed to step 3:
75 can be fit into 251 3 times, resulting in a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 26 after subtracting 225 from 251.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 75

On to step 4:
268 divided by 75 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtract 225 from 268 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 75

Let's proceed to step 5:
When dividing 438 by 75, we get 5 with a remainder of 63.
The next digit of our result is 5. 
Result so far: 335.0
If we subtract 375 from 438, we get 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 75

Going ahead to step 6:
The number 75 fits into 632 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 3358.0
Subtracting 600 from 632 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
75 can be fit into 320 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 3358.4
Deduct 300 from 320 and we're left 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:
75 goes into 200 2 times with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 3358.42
If we subtract 150 from 200, we 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.

Moving on to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 3358.426
If we take 450 away from 500, we end up 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 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 3358.4266
Subtracting 450 from 500 leaves us 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.

Our division results in 3358.4266 with a remaining 0.0005.
