We divide 1968287 by 869
The aim is to understand the frequency of 869 in 1968287.

Let's proceed to step 1:
The number 869 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 869

Step 2:
869 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 869

Going ahead to step 3:
869 goes into 196 0 times with a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Include the next digit (8) from the dividend after 196, then repeat: 1968 / 869

Advancing to step 4:
869 goes into 1968 2 times with a remainder of 230.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1738 from 1968 to get 230.
Fetch the next digit (2) from the dividend, attach it to 230 and continue: 2302 / 869

Moving on to step 5:
869 can be fit into 2302 2 times, resulting in a remainder of 564.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1738 from 2302 to get 564.
Take the next digit (8) from the dividend and append it to 564, then repeat: 5648 / 869

On to step 6:
5648 divided by 869 is 6 with a remainder of 434.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
If we take 5214 away from 5648, we end up with 434.
Append the next digit (7) from the dividend to 434 and continue with: 4347 / 869

Going ahead to step 7:
When dividing 4347 by 869, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 2265.0
Subtract 4345 from 4347 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 869 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2265.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 869 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 2265.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 2265.0 with a remainder of 0.2.
