Let's divide 91754845 by 5
The aim is to understand the frequency of 5 in 91754845.

On to step 1:
The number 5 fits into 9 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 5 away from 9, we end up with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 5

Going ahead to step 2:
If we divide 41 by 5, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 18.0
If we take 40 away from 41, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 5

Step 3:
The number 5 fits into 17 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we take 15 away from 17, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 5

On to step 4:
If we divide 25 by 5, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1835.0
The remainder is 0 after subtracting 25 from 25.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 5

Moving on to step 5:
If we divide 4 by 5, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 18350.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 5

Moving on to step 6:
48 divided by 5 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 183509.0
If we subtract 45 from 48, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 5

Advancing to step 7:
The number 5 fits into 34 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1835096.0
Subtract 30 from 34 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 5

On to step 8:
45 divided by 5 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 18350969.0
Subtracting 45 from 45 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.

Going ahead to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 18350969.0
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 10:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 18350969.0
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 18350969.0 and a remainder of 0.0.
