27897312 ÷ 865 
The aim is to understand the frequency of 865 in 27897312.

On to step 1:
When dividing 2 by 865, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 865

Going ahead to step 2:
The number 865 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 865

Step 3:
865 goes into 278 0 times with a remainder of 278.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 278 and we're left with 278.
Include the next digit (9) from the dividend after 278, then repeat: 2789 / 865

Advancing to step 4:
When dividing 2789 by 865, we get 3 with a remainder of 194.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 194 after subtracting 2595 from 2789.
Include the next digit (7) from the dividend after 194, then repeat: 1947 / 865

Let's proceed to step 5:
865 goes into 1947 2 times with a remainder of 217.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 1730 from 1947, we get 217.
Append the next digit (3) from the dividend to 217 and continue with: 2173 / 865

Advancing to step 6:
The number 865 fits into 2173 2 times, leaving a remainder of 443.
The number 2 becomes the next digit in our result. 
Result so far: 322.0
The remainder is 443 after subtracting 1730 from 2173.
Grab the next digit (1) from the dividend, add it to 443, then carry on: 4431 / 865

Advancing to step 7:
4431 divided by 865 is 5 with a remainder of 106.
Write down 5 as next digit of the result. 
Result so far: 3225.0
Subtract 4325 from 4431 to get 106.
Include the next digit (2) from the dividend after 106, then repeat: 1062 / 865

Step 8:
865 goes into 1062 1 times with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 32251.0
Deduct 865 from 1062 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 9:
The number 865 fits into 1970 2 times, leaving a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 32251.2
The remainder is 240 after subtracting 1730 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
The number 865 fits into 2400 2 times, leaving a remainder of 670.
The number 2 becomes the next digit in our result. 
Result so far: 32251.22
If we take 1730 away from 2400, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

After the division, we end up with 32251.22 and a remainder of 0.67.
