We divide 66044049 by 5
The aim is to understand the frequency of 5 in 66044049.

Advancing to step 1:
When dividing 6 by 5, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 5

Advancing to step 2:
The number 5 fits into 16 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 15 from 16, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 5

Moving on to step 3:
If we divide 10 by 5, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
The remainder is 0 after subtracting 10 from 10.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 5

On to step 4:
5 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1320.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 5

Step 5:
44 divided by 5 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 13208.0
If we subtract 40 from 44, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 5

Going ahead to step 6:
If we divide 40 by 5, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 132088.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 5

On to step 7:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1320880.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 5

Going ahead to step 8:
If we divide 49 by 5, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 13208809.0
If we take 45 away from 49, 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 9:
5 can be fit into 40 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 13208809.8
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.

On to step 10:
If we divide 0 by 5, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13208809.8
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.

Step 11:
If we divide 0 by 5, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13208809.8
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.

After the division, we end up with 13208809.8 and a remainder of 0.0.
