Let's divide 777950 by 75
The aim is to understand the frequency of 75 in 777950.

Going ahead to step 1:
75 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 75

Step 2:
75 can be fit into 77 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 75 from 77.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 75

Let's proceed to step 3:
75 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 27 to get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 75

Step 4:
When dividing 279 by 75, we get 3 with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 225 away from 279, we end up with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 75

Step 5:
545 divided by 75 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 1037.0
If we take 525 away from 545, we end up with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 75

On to step 6:
75 can be fit into 200 2 times, resulting in a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 10372.0
Deduct 150 from 200 and we're left 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 7:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 10372.6
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.

Going ahead to step 8:
If we divide 500 by 75, we get 6 and a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 10372.66
If we subtract 450 from 500, we 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 10372.66 with a remainder of 0.05.
