We're dividing 815217 by 50 
The aim is to understand the frequency of 50 in 815217.

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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 50

Let's proceed to step 2:
50 can be fit into 81 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 50 from 81 to get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 50

Advancing to step 3:
50 goes into 315 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 15 after subtracting 300 from 315.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 50

Step 4:
When dividing 152 by 50, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
The remainder is 2 after subtracting 150 from 152.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 50

Let's proceed to step 5:
The number 50 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 1630.0
Subtract 0 from 21 to get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 50

Advancing to step 6:
217 divided by 50 is 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 16304.0
If we subtract 200 from 217, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
The number 50 fits into 170 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 16304.3
Subtract 150 from 170 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
50 goes into 200 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 16304.34
Subtract 200 from 200 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.

Step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 16304.34
Subtracting 0 from 0 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.

On to step 10:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16304.34
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.

In conclusion, the division gives 16304.34 with a balance of 0.0.
