We're dividing 785600 by 75 
The aim is to understand the frequency of 75 in 785600.

Advancing to step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 75

Let's proceed to step 2:
75 can be fit into 78 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 75 from 78 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 75

Advancing to step 3:
When dividing 35 by 75, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 75

Let's proceed to step 4:
When dividing 356 by 75, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 300 away from 356, we end up with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 75

On to step 5:
75 can be fit into 560 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 1047.0
If we subtract 525 from 560, we get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 75

Step 6:
When dividing 350 by 75, we get 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 10474.0
The remainder is 50 after subtracting 300 from 350.
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 7:
When dividing 500 by 75, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 10474.6
Subtracting 450 from 500 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.

Going ahead to step 8:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 10474.66
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.

After the division, we end up with 10474.66 and a remainder of 0.05.
