615015 divided by 50 
The aim is to understand the frequency of 50 in 615015.

Step 1:
50 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 50

Advancing to step 2:
If we divide 61 by 50, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 50 away from 61, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 50

Moving on to step 3:
If we divide 115 by 50, we get 2 and a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 100 from 115 and we're left with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 50

On to step 4:
150 divided by 50 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 150 from 150 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 50

Advancing to step 5:
When dividing 1 by 50, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1230.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 50

Step 6:
The number 50 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 12300.0
If we take 0 away from 15, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
50 can be fit into 150 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 12300.3
If we take 150 away from 150, 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.

Step 8:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12300.3
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:
50 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12300.3
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.

Our division results in 12300.3 with a remaining 0.0.
