We look at the division of 238091 by 45 
The aim is to understand the frequency of 45 in 238091.

Let's proceed to step 1:
45 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 45

Going ahead to step 2:
23 divided by 45 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 45

Going ahead to step 3:
45 goes into 238 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 225 from 238 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 45

Let's proceed to step 4:
The number 45 fits into 130 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 90 from 130 leaves us with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 45

Moving on to step 5:
If we divide 409 by 45, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 529.0
Subtract 405 from 409 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 45

Step 6:
45 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 5290.0
The remainder is 41 after subtracting 0 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
When dividing 410 by 45, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 5290.9
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 5290.91
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 5290.911
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 5290.911, with a leftover of 0.0005.
