We're dividing 42937 by 50 
The aim is to understand the frequency of 50 in 42937.

Step 1:
The number 50 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 50

Moving on to step 2:
When dividing 42 by 50, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 50

Let's proceed to step 3:
If we divide 429 by 50, we get 8 and a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 400 from 429, we get 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 50

Moving on to step 4:
50 goes into 293 5 times with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 250 away from 293, we end up with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 50

Let's proceed to step 5:
50 can be fit into 437 8 times, resulting in a remainder of 37.
The next digit of our result is 8. 
Result so far: 858.0
If we subtract 400 from 437, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 6:
50 can be fit into 370 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 858.7
If we subtract 350 from 370, we get 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 7:
50 can be fit into 200 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 858.74
Deduct 200 from 200 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 8:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 858.74
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.

On to step 9:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 858.74
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 quotient of the division is 858.74, and the remainder is 0.0.
