We look at the division of 307758 by 50 
The aim is to understand the frequency of 50 in 307758.

Advancing to step 1:
50 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 50

Moving on to step 2:
If we divide 30 by 50, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 50

Advancing to step 3:
The number 50 fits into 307 6 times, leaving a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 300 from 307 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 50

Step 4:
50 can be fit into 77 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 50 away from 77, we end up with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 50

Moving on to step 5:
50 goes into 275 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 615.0
The remainder is 25 after subtracting 250 from 275.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 50

Moving on to step 6:
The number 50 fits into 258 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 6155.0
Deduct 250 from 258 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
50 can be fit into 80 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 6155.1
Deduct 50 from 80 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 50 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6155.16
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.

On to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6155.16
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.

Let's proceed to step 10:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6155.16
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.

After the division, we end up with 6155.16 and a remainder of 0.0.
