We're dividing 137076 by 45 
The aim is to understand the frequency of 45 in 137076.

Moving on to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 45

Step 2:
45 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 45

Step 3:
If we divide 137 by 45, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 135 from 137 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 45

Let's proceed to step 4:
45 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 45

Advancing to step 5:
45 can be fit into 207 4 times, resulting in a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
Subtracting 180 from 207 leaves us with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 45

Advancing to step 6:
276 divided by 45 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3046.0
Subtract 270 from 276 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 45, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 3046.1
If we subtract 45 from 60, we get 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.
Write down 3 as next digit of the result. 
Result so far: 3046.13
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.

Step 9:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 3046.133
If we subtract 135 from 150, we get 15.
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 outcome is 3046.133, with a leftover of 0.0015.
