Let's divide 666453 by 5
The aim is to understand the frequency of 5 in 666453.

On to step 1:
6 divided by 5 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 5 away from 6, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 5

Let's proceed to step 2:
When dividing 16 by 5, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 15 from 16, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 5

Advancing to step 3:
5 goes into 16 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 15 away from 16, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 5

On to step 4:
If we divide 14 by 5, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1332.0
Subtracting 10 from 14 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 5

Going ahead to step 5:
5 can be fit into 45 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 13329.0
The remainder is 0 after subtracting 45 from 45.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 5

Let's proceed to step 6:
5 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 133290.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 133290.6
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 5 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 133290.6
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.

Moving on to step 9:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 133290.6
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 quotient of the division is 133290.6, and the remainder is 0.0.
