We're dividing 363117 by 45 
The aim is to understand the frequency of 45 in 363117.

Let's proceed to step 1:
3 divided by 45 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 45

Going ahead to step 2:
The number 45 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 45

On to step 3:
When dividing 363 by 45, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
If we take 360 away from 363, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 45

Going ahead to step 4:
If we divide 31 by 45, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 45

On to step 5:
45 goes into 311 6 times with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
If we take 270 away from 311, we end up with 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 45

Moving on to step 6:
When dividing 417 by 45, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 8069.0
Deduct 405 from 417 and we're left 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.

Going ahead to step 7:
45 goes into 120 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 8069.2
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.

Advancing to step 8:
45 goes into 300 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 8069.26
Subtracting 270 from 300 leaves us 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.

Let's proceed to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 8069.266
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 result is 8069.266 with a remainder of 0.003.
