537320 ÷ 45 
The aim is to understand the frequency of 45 in 537320.

Advancing to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 45

Let's proceed to step 2:
If we divide 53 by 45, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 53 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 45

Advancing to step 3:
87 divided by 45 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 42 after subtracting 45 from 87.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 45

Moving on to step 4:
When dividing 423 by 45, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 405 from 423, we get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 45

Let's proceed to step 5:
The number 45 fits into 182 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1194.0
If we subtract 180 from 182, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

Step 6:
The number 45 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11940.0
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 7:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11940.4
Subtracting 180 from 200 leaves us 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.

Going ahead to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11940.44
If we take 180 away from 200, we end up 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.

In conclusion, the division gives 11940.44 with a balance of 0.02.
