We're dividing 383879 by 50 
The aim is to understand the frequency of 50 in 383879.

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
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 50

On to step 2:
50 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 50

Going ahead to step 3:
50 goes into 383 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 350 from 383 and we're left with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 50

Advancing to step 4:
When dividing 338 by 50, we get 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we take 300 away from 338, we end up with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 50

Going ahead to step 5:
If we divide 387 by 50, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 767.0
If we subtract 350 from 387, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 50

Going ahead to step 6:
When dividing 379 by 50, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 7677.0
Subtracting 350 from 379 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
If we divide 290 by 50, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 7677.5
The remainder is 40 after subtracting 250 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 7677.58
Deduct 400 from 400 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:
If we divide 0 by 50, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7677.58
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.

Let's proceed to step 10:
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: 7677.58
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.

The final outcome is 7677.58, with a leftover of 0.0.
