We look at the division of 396075 by 50 
The aim is to understand the frequency of 50 in 396075.

On to step 1:
50 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 50

Step 2:
50 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 50

Going ahead to step 3:
If we divide 396 by 50, we get 7 and a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 350 from 396 and we're left with 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 50

On to step 4:
460 divided by 50 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 10 after subtracting 450 from 460.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 50

Moving on to step 5:
When dividing 107 by 50, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 792.0
Deduct 100 from 107 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 50

Moving on to step 6:
The number 50 fits into 75 1 times, leaving a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 7921.0
Deduct 50 from 75 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
250 divided by 50 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7921.5
Subtract 250 from 250 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 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7921.5
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.

Moving on to step 9:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7921.5
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.

The final result is 7921.5 with a remainder of 0.0.
