We look at the division of 75528 by 50 
The aim is to understand the frequency of 50 in 75528.

Going ahead to step 1:
The number 50 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 50

Let's proceed to step 2:
50 goes into 75 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 50 from 75 leaves us with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 50

On to step 3:
The number 50 fits into 255 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 250 from 255 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 50

Let's proceed to step 4:
52 divided by 50 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we subtract 50 from 52, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 50

Step 5:
When dividing 28 by 50, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 1510.0
Subtracting 0 from 28 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 6:
280 divided by 50 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1510.5
Subtracting 250 from 280 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 50 fits into 300 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1510.56
If we subtract 300 from 300, we 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 8:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1510.56
If we subtract 0 from 0, we 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.

Let's proceed to step 9:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1510.56
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.

After the division, we end up with 1510.56 and a remainder of 0.0.
