We look at the division of 254489 by 45 
The aim is to understand the frequency of 45 in 254489.

Going ahead to step 1:
45 goes into 2 0 times with 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.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 45

Let's proceed to step 2:
25 divided by 45 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 45

Let's proceed to step 3:
254 divided by 45 is 5 with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 225 from 254 and we're left with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 45

Advancing to step 4:
If we divide 294 by 45, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 270 from 294 and we're left with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 45

Going ahead to step 5:
45 goes into 248 5 times with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 565.0
The remainder is 23 after subtracting 225 from 248.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 45

Going ahead to step 6:
45 can be fit into 239 5 times, resulting in a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5655.0
The remainder is 14 after subtracting 225 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 45, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 5655.3
Subtract 135 from 140 to 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.

Advancing to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 5655.31
Deduct 45 from 50 and we're left 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.

Let's proceed to step 9:
When dividing 50 by 45, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 5655.311
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.

In conclusion, the division gives 5655.311 with a balance of 0.0005.
