We divide 850931 by 50
The aim is to understand the frequency of 50 in 850931.

Step 1:
When dividing 8 by 50, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 50

Let's proceed to step 2:
If we divide 85 by 50, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 50 away from 85, we end up with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 50

Advancing to step 3:
50 can be fit into 350 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 350 from 350 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 50

Moving on to step 4:
50 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtract 0 from 9 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 50

Step 5:
93 divided by 50 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1701.0
If we take 50 away from 93, we end up with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 50

Let's proceed to step 6:
50 can be fit into 431 8 times, resulting in a remainder of 31.
The next digit of our result is 8. 
Result so far: 17018.0
Subtracting 400 from 431 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
If we divide 310 by 50, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 17018.6
Deduct 300 from 310 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.

Moving on to step 8:
50 goes into 100 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 17018.62
Subtracting 100 from 100 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.

Advancing to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17018.62
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.

On to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17018.62
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 final outcome is 17018.62, with a leftover of 0.0.
