Let's divide 678080 by 75
The aim is to understand the frequency of 75 in 678080.

Moving on to step 1:
75 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 75

Step 2:
75 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 75

Going ahead to step 3:
When dividing 678 by 75, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 675 away from 678, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 75

Moving on to step 4:
The number 75 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 30 to get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 75

Advancing to step 5:
The number 75 fits into 308 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 904.0
Subtracting 300 from 308 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 75

On to step 6:
75 goes into 80 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 9041.0
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 75, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9041.0
If we take 0 away from 50, 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.

Step 8:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 9041.06
The remainder is 50 after subtracting 450 from 500.
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 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 9041.066
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 9041.066 with a remainder of 0.005.
