We look at the division of 396896 by 50 
The aim is to understand the frequency of 50 in 396896.

Advancing to step 1:
3 divided by 50 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 50

Advancing to step 2:
50 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 50

Advancing to step 3:
When dividing 396 by 50, we get 7 with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 350 from 396 and we're left with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 50

Let's proceed to step 4:
50 can be fit into 468 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 18 after subtracting 450 from 468.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 50

Advancing to step 5:
If we divide 189 by 50, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 793.0
The remainder is 39 after subtracting 150 from 189.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 50

Step 6:
396 divided by 50 is 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 7937.0
Subtracting 350 from 396 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
460 divided by 50 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 7937.9
Subtract 450 from 460 to get 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.
Write down 2 as next digit of the result. 
Result so far: 7937.92
Deduct 100 from 100 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.

Going ahead to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7937.92
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.

Advancing to step 10:
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: 7937.92
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.

Our division results in 7937.92 with a remaining 0.0.
