We're dividing 287951 by 50 
The aim is to understand the frequency of 50 in 287951.

Let's proceed to step 1:
When dividing 2 by 50, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 50

Let's proceed to step 2:
When dividing 28 by 50, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 50

Going ahead to step 3:
If we divide 287 by 50, we get 5 and a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 250 from 287 to get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 50

Step 4:
50 goes into 379 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 350 from 379 and we're left with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 50

Let's proceed to step 5:
When dividing 295 by 50, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
The remainder is 45 after subtracting 250 from 295.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 50

Moving on to step 6:
451 divided by 50 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 5759.0
Deduct 450 from 451 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 50, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5759.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
50 goes into 100 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 5759.02
Subtract 100 from 100 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 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5759.02
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.

On to step 10:
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: 5759.02
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.

After the division, we end up with 5759.02 and a remainder of 0.0.
