We look at the division of 750231 by 50 
The aim is to understand the frequency of 50 in 750231.

Let's proceed to step 1:
50 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 50

On to step 2:
If we divide 75 by 50, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 50 from 75 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 50

On to step 3:
50 goes into 250 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 250 from 250 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 50

Let's proceed to step 4:
When dividing 2 by 50, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 150.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 50

Advancing to step 5:
When dividing 23 by 50, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 1500.0
If we take 0 away from 23, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 50

On to step 6:
If we divide 231 by 50, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 15004.0
Deduct 200 from 231 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
310 divided by 50 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 15004.6
Subtracting 300 from 310 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 50, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 15004.62
If we subtract 100 from 100, 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.

Advancing to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15004.62
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.

Moving on to step 10:
50 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15004.62
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.

The final result is 15004.62 with a remainder of 0.0.
