We look at the division of 49149868 by 5 
The aim is to understand the frequency of 5 in 49149868.

Advancing to step 1:
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: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 5

Going ahead to step 2:
When dividing 49 by 5, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 4 after subtracting 45 from 49.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 5

Going ahead to step 3:
If we divide 41 by 5, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 40 away from 41, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 5

Moving on to step 4:
5 can be fit into 14 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 982.0
Subtract 10 from 14 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 5

Step 5:
5 can be fit into 49 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 9829.0
Subtracting 45 from 49 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 5

Let's proceed to step 6:
5 can be fit into 48 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 98299.0
Deduct 45 from 48 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 5

Going ahead to step 7:
36 divided by 5 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 982997.0
Deduct 35 from 36 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 5

Let's proceed to step 8:
18 divided by 5 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 9829973.0
Deduct 15 from 18 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
5 goes into 30 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 9829973.6
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.

Advancing to step 10:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9829973.6
Deduct 0 from 0 and we're left 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.

Moving on to step 11:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9829973.6
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.

The final result is 9829973.6 with a remainder of 0.0.
