We look at the division of 727510 by 50 
The aim is to understand the frequency of 50 in 727510.

On to step 1:
7 divided by 50 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 50

Step 2:
50 goes into 72 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 50 from 72 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 50

On to step 3:
227 divided by 50 is 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 200 from 227 and we're left with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 50

Going ahead to step 4:
The number 50 fits into 275 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Subtracting 250 from 275 leaves us with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 50

Step 5:
The number 50 fits into 251 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 1455.0
If we subtract 250 from 251, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 50

Step 6:
10 divided by 50 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 14550.0
Deduct 0 from 10 and we're left 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.

Step 7:
100 divided by 50 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 14550.2
If we take 100 away from 100, we end up 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.

Step 8:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14550.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14550.2
Deduct 0 from 0 and we're left 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 14550.2 and a remainder of 0.0.
