We look at the division of 950191 by 45 
The aim is to understand the frequency of 45 in 950191.

Going ahead to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 45

On to step 2:
45 can be fit into 95 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 5 after subtracting 90 from 95.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 45

Advancing to step 3:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 45 away from 50, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 45

Moving on to step 4:
51 divided by 45 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 211.0
Deduct 45 from 51 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 45

Moving on to step 5:
If we divide 69 by 45, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 2111.0
The remainder is 24 after subtracting 45 from 69.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 45

Step 6:
241 divided by 45 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 21115.0
If we take 225 away from 241, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 45 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 21115.3
Subtracting 135 from 160 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 21115.35
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 21115.355
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 21115.355 with a remaining 0.0025.
