Let's divide 930405 by 50
The aim is to understand the frequency of 50 in 930405.

Step 1:
50 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 50

On to step 2:
If we divide 93 by 50, we get 1 and a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 50 away from 93, we end up with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 50

Let's proceed to step 3:
If we divide 430 by 50, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 400 away from 430, we end up with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 50

Going ahead to step 4:
50 goes into 304 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 186.0
If we take 300 away from 304, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 50

Moving on to step 5:
When dividing 40 by 50, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1860.0
If we take 0 away from 40, we end up with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 50

On to step 6:
405 divided by 50 is 8 with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 18608.0
If we take 400 away from 405, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 can be fit into 50 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 18608.1
Subtracting 50 from 50 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 8:
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: 18608.1
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.

Step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18608.1
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 result is 18608.1 with a remainder of 0.0.
