We look at the division of 289500 by 45 
The aim is to understand the frequency of 45 in 289500.

Let's proceed to step 1:
45 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 45

Advancing to step 2:
45 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 45

Step 3:
When dividing 289 by 45, we get 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 270 from 289 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 45

Moving on to step 4:
The number 45 fits into 195 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 180 from 195, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 45

Moving on to step 5:
If we divide 150 by 45, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
If we take 135 away from 150, we end up with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 45

Going ahead to step 6:
If we divide 150 by 45, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 6433.0
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
If we divide 150 by 45, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 6433.3
Deduct 135 from 150 and we're left 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:
When dividing 150 by 45, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 6433.33
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 6433.33 with a remainder of 0.015.
