We look at the division of 78360494 by 75 
The aim is to understand the frequency of 75 in 78360494.

Going ahead to step 1:
75 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 75

Let's proceed to step 2:
75 goes into 78 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 75 away from 78, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 75

On to step 3:
If we divide 33 by 75, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 75

On to step 4:
75 goes into 336 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we subtract 300 from 336, we get 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 75

Let's proceed to step 5:
360 divided by 75 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1044.0
Subtract 300 from 360 to get 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 75

Going ahead to step 6:
75 can be fit into 604 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10448.0
If we subtract 600 from 604, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 75

Moving on to step 7:
75 can be fit into 49 0 times, resulting in a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 104480.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 75

Advancing to step 8:
75 can be fit into 494 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 1044806.0
The remainder is 44 after subtracting 450 from 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
75 can be fit into 440 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 1044806.5
Subtracting 375 from 440 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
75 goes into 650 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 1044806.58
Subtracting 600 from 650 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 1044806.586
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
When dividing 500 by 75, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 1044806.5866
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 1044806.5866 with a remainder of 0.0005.
