We look at the division of 616093 by 45 
The aim is to understand the frequency of 45 in 616093.

Advancing to step 1:
45 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 45

Advancing to step 2:
61 divided by 45 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 61 and we're left with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 45

Going ahead to step 3:
166 divided by 45 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 135 from 166 leaves us with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 45

Step 4:
45 can be fit into 310 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Deduct 270 from 310 and we're left with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 45

Step 5:
The number 45 fits into 409 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 1369.0
The remainder is 4 after subtracting 405 from 409.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 45

Going ahead to step 6:
43 divided by 45 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 13690.0
If we subtract 0 from 43, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 45 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 13690.9
If we take 405 away from 430, we end up 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.

Advancing to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 13690.95
If we take 225 away from 250, we end up 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 9:
250 divided by 45 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 13690.955
If we subtract 225 from 250, we 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.

The final outcome is 13690.955, with a leftover of 0.0025.
