250290 divided by 75 
The aim is to understand the frequency of 75 in 250290.

On to step 1:
The number 75 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 75

Let's proceed to step 2:
The number 75 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 75

On to step 3:
250 divided by 75 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 225 away from 250, we end up with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 75

Moving on to step 4:
75 goes into 252 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 225 from 252 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 75

On to step 5:
When dividing 279 by 75, we get 3 with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 333.0
Subtract 225 from 279 to get 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 75

Let's proceed to step 6:
75 goes into 540 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 3337.0
The remainder is 15 after subtracting 525 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 75 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3337.2
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 75, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3337.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3337.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3337.2 and a remainder of 0.0.
