We look at the division of 678255 by 45 
The aim is to understand the frequency of 45 in 678255.

Let's proceed to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 45

On to step 2:
45 can be fit into 67 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 67 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 45

Going ahead to step 3:
45 goes into 228 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 15.0
If we take 225 away from 228, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 45

Advancing to step 4:
When dividing 32 by 45, we get 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 150.0
If we take 0 away from 32, we end up with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 45

Step 5:
When dividing 325 by 45, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1507.0
Subtracting 315 from 325 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 45

Step 6:
45 goes into 105 2 times with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 15072.0
The remainder is 15 after subtracting 90 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 15072.3
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 15072.33
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 15072.33 with a balance of 0.015.
