We look at the division of 386503 by 50 
The aim is to understand the frequency of 50 in 386503.

Moving on to step 1:
50 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 50

Let's proceed to step 2:
When dividing 38 by 50, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 50

Going ahead to step 3:
50 goes into 386 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 350 from 386, we get 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 50

Moving on to step 4:
50 can be fit into 365 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 77.0
The remainder is 15 after subtracting 350 from 365.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 50

Let's proceed to step 5:
50 goes into 150 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 773.0
If we take 150 away from 150, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 50

Going ahead to step 6:
3 divided by 50 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 7730.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 50, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7730.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
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: 7730.06
Deduct 300 from 300 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.

Step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7730.06
If we take 0 away from 0, 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.

Let's proceed to step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7730.06
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.

The quotient of the division is 7730.06, and the remainder is 0.0.
