We're dividing 215717 by 5 
The aim is to understand the frequency of 5 in 215717.

Moving on to step 1:
5 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 5

Going ahead to step 2:
When dividing 21 by 5, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 20 from 21.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 5

Let's proceed to step 3:
When dividing 15 by 5, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 15 from 15 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 5

Step 4:
When dividing 7 by 5, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 431.0
If we subtract 5 from 7, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 5

Let's proceed to step 5:
5 goes into 21 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4314.0
If we take 20 away from 21, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 5

Let's proceed to step 6:
When dividing 17 by 5, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 43143.0
Subtract 15 from 17 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 5, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 43143.4
Subtracting 20 from 20 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:
0 divided by 5 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43143.4
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.

Let's proceed to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43143.4
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.

The final result is 43143.4 with a remainder of 0.0.
