Let's divide 627601 by 45
The aim is to understand the frequency of 45 in 627601.

Going ahead to step 1:
If we divide 6 by 45, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 45

Going ahead to step 2:
When dividing 62 by 45, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 45 from 62.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 45

Advancing to step 3:
45 goes into 177 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 42 after subtracting 135 from 177.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 45

Let's proceed to step 4:
If we divide 426 by 45, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 405 from 426 to get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 45

Moving on to step 5:
210 divided by 45 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 1394.0
If we subtract 180 from 210, we get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 45

On to step 6:
If we divide 301 by 45, we get 6 and a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 13946.0
The remainder is 31 after subtracting 270 from 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
When dividing 310 by 45, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 13946.6
Subtract 270 from 310 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 13946.68
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 13946.688
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 13946.688 with a balance of 0.004.
