230984 ÷ 45 
The aim is to understand the frequency of 45 in 230984.

Advancing to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 45

Moving on to step 2:
The number 45 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 45

Let's proceed to step 3:
The number 45 fits into 230 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 225 away from 230, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 45

Going ahead to step 4:
If we divide 59 by 45, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 45 from 59, we get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 45

Advancing to step 5:
45 goes into 148 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 513.0
Subtract 135 from 148 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 45

Step 6:
134 divided by 45 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 5132.0
If we take 90 away from 134, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
When dividing 440 by 45, we get 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 5132.9
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 5132.97
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 5132.977
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 5132.977 and a remainder of 0.0035.
