We're dividing 128874 by 50 
The aim is to understand the frequency of 50 in 128874.

On to step 1:
1 divided by 50 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 50

Advancing to step 2:
If we divide 12 by 50, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 50

Moving on to step 3:
50 goes into 128 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 100 away from 128, we end up with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 50

Going ahead to step 4:
50 goes into 288 5 times with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 250 from 288 and we're left with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 50

Advancing to step 5:
387 divided by 50 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 257.0
Subtract 350 from 387 to get 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 50

Moving on to step 6:
50 goes into 374 7 times with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 2577.0
The remainder is 24 after subtracting 350 from 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
50 goes into 240 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 2577.4
If we take 200 away from 240, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 50 fits into 400 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2577.48
The remainder is 0 after subtracting 400 from 400.
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:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2577.48
The remainder is 0 after subtracting 0 from 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 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2577.48
The remainder is 0 after subtracting 0 from 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 quotient of the division is 2577.48, and the remainder is 0.0.
