861202 ÷ 75 
The aim is to understand the frequency of 75 in 861202.

Step 1:
8 divided by 75 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 75

Going ahead to step 2:
75 can be fit into 86 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 86 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 75

Step 3:
111 divided by 75 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 36 after subtracting 75 from 111.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 75

Let's proceed to step 4:
When dividing 362 by 75, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we subtract 300 from 362, we get 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 75

Moving on to step 5:
75 goes into 620 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 1148.0
Subtracting 600 from 620 leaves us with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 75

Step 6:
If we divide 202 by 75, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 11482.0
The remainder is 52 after subtracting 150 from 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
When dividing 520 by 75, we get 6 with a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 11482.6
Deduct 450 from 520 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 75, we get 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 11482.69
Deduct 675 from 700 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 11482.693
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 11482.6933
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 11482.6933 with a remainder of 0.00025.
