We're dividing 266987 by 50 
The aim is to understand the frequency of 50 in 266987.

Advancing to step 1:
2 divided by 50 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 50

Going ahead to step 2:
The number 50 fits into 26 0 times, leaving a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 50

Let's proceed to step 3:
50 can be fit into 266 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 250 from 266 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 50

Step 4:
50 goes into 169 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 150 from 169 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 50

Let's proceed to step 5:
50 can be fit into 198 3 times, resulting in a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 533.0
Subtracting 150 from 198 leaves us with 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 50

Moving on to step 6:
50 goes into 487 9 times with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 5339.0
Deduct 450 from 487 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
50 can be fit into 370 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 5339.7
Subtracting 350 from 370 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 50 fits into 200 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 5339.74
Subtracting 200 from 200 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.

On to step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5339.74
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.

Moving on to step 10:
0 divided by 50 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5339.74
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.

In conclusion, the division gives 5339.74 with a balance of 0.0.
