Let's divide 78197075 by 45
The aim is to understand the frequency of 45 in 78197075.

Moving on to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 45

Going ahead to step 2:
78 divided by 45 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 78, we get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 45

Moving on to step 3:
331 divided by 45 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 315 from 331 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 45

Advancing to step 4:
When dividing 169 by 45, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Subtract 135 from 169 to get 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 45

On to step 5:
45 can be fit into 347 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1737.0
If we subtract 315 from 347, we get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 45

On to step 6:
If we divide 320 by 45, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 17377.0
If we take 315 away from 320, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 45

Going ahead to step 7:
45 goes into 57 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 173771.0
If we take 45 away from 57, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 45

Step 8:
45 goes into 125 2 times with a remainder of 35.
The next digit of our result is 2. 
Result so far: 1737712.0
If we take 90 away from 125, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 1737712.7
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
When dividing 350 by 45, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 1737712.77
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 1737712.77 with a remainder of 0.035.
