We're dividing 902885 by 50 
The aim is to understand the frequency of 50 in 902885.

Let's proceed to step 1:
50 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 50

Let's proceed to step 2:
50 can be fit into 90 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 50 from 90 leaves us with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 50

Moving on to step 3:
50 goes into 402 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 18.0
If we take 400 away from 402, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 50

Advancing to step 4:
28 divided by 50 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 180.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 50

Advancing to step 5:
288 divided by 50 is 5 with a remainder of 38.
The next digit of our result is 5. 
Result so far: 1805.0
Subtract 250 from 288 to get 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 50

Step 6:
50 goes into 385 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 18057.0
Deduct 350 from 385 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 50 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 18057.7
Subtract 350 from 350 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 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: 18057.7
Deduct 0 from 0 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.

Let's proceed 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: 18057.7
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.

Our division results in 18057.7 with a remaining 0.0.
