We look at the division of 318105 by 45 
The aim is to understand the frequency of 45 in 318105.

Step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 45

Step 2:
If we divide 31 by 45, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 45

Advancing to step 3:
When dividing 318 by 45, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 315 from 318 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 45

Let's proceed to step 4:
31 divided by 45 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 45

Let's proceed to step 5:
If we divide 310 by 45, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
Deduct 270 from 310 and we're left with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 45

Let's proceed to step 6:
The number 45 fits into 405 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 7069.0
Subtracting 405 from 405 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7069.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7069.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 7069.0 with a balance of 0.0.
