We're dividing 752727 by 45 
The aim is to understand the frequency of 45 in 752727.

On to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 45

Step 2:
When dividing 75 by 45, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 75 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 45

Going ahead to step 3:
45 can be fit into 302 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 270 from 302 leaves us with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 45

On to step 4:
327 divided by 45 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 167.0
Subtract 315 from 327 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 45

Going ahead to step 5:
45 can be fit into 122 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1672.0
If we take 90 away from 122, we end up with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 45

Advancing to step 6:
327 divided by 45 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 16727.0
Subtracting 315 from 327 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 45 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 16727.2
If we take 90 away from 120, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 16727.26
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
45 goes into 300 6 times with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 16727.266
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 16727.266, with a leftover of 0.003.
