We look at the division of 109073 by 45 
The aim is to understand the frequency of 45 in 109073.

On to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 45

Going ahead to step 2:
When dividing 10 by 45, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 45

Moving on to step 3:
If we divide 109 by 45, we get 2 and a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 90 from 109 to get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 45

Moving on to step 4:
The number 45 fits into 190 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 180 from 190, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 45

On to step 5:
45 can be fit into 107 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 242.0
Deduct 90 from 107 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 45

Moving on to step 6:
If we divide 173 by 45, we get 3 and a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 2423.0
Subtract 135 from 173 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 45 fits into 380 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 2423.8
Deduct 360 from 380 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 2423.84
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 45, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 2423.844
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2423.844, with a leftover of 0.002.
