We look at the division of 921719 by 5 
The aim is to understand the frequency of 5 in 921719.

Moving on to step 1:
When dividing 9 by 5, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 5 from 9.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 5

Advancing to step 2:
5 can be fit into 42 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 40 from 42 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 5

Going ahead to step 3:
When dividing 21 by 5, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
The remainder is 1 after subtracting 20 from 21.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 5

Going ahead to step 4:
The number 5 fits into 17 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 1843.0
Deduct 15 from 17 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 5

Moving on to step 5:
If we divide 21 by 5, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 18434.0
Deduct 20 from 21 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 5

Let's proceed to step 6:
19 divided by 5 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 184343.0
If we take 15 away from 19, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 5 fits into 40 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 184343.8
Subtracting 40 from 40 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:
5 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 184343.8
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.

On to step 9:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 184343.8
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.

After the division, we end up with 184343.8 and a remainder of 0.0.
