905199 divided by 50 
The aim is to understand the frequency of 50 in 905199.

Moving on to step 1:
If we divide 9 by 50, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 50

Step 2:
90 divided by 50 is 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 50 from 90 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 50

Step 3:
When dividing 405 by 50, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 400 from 405, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 50

Advancing to step 4:
The number 50 fits into 51 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we subtract 50 from 51, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 50

Advancing to step 5:
The number 50 fits into 19 0 times, leaving a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 1810.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 50

Moving on to step 6:
The number 50 fits into 199 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 18103.0
If we subtract 150 from 199, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
50 goes into 490 9 times with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 18103.9
Subtracting 450 from 490 leaves us 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.

Advancing to step 8:
50 goes into 400 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18103.98
Subtract 400 from 400 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:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 18103.98
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.

Let's proceed to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18103.98
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 18103.98 with a remaining 0.0.
