84453987 divided by 865 
The aim is to understand the frequency of 865 in 84453987.

Moving on to step 1:
When dividing 8 by 865, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 865

Going ahead to step 2:
84 divided by 865 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 865

Let's proceed to step 3:
The number 865 fits into 844 0 times, leaving a remainder of 844.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 844 to get 844.
Take the next digit (5) from the dividend and append it to 844, then repeat: 8445 / 865

Step 4:
865 goes into 8445 9 times with a remainder of 660.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7785 from 8445 to get 660.
Take the next digit (3) from the dividend and append it to 660, then repeat: 6603 / 865

On to step 5:
If we divide 6603 by 865, we get 7 and a remainder of 548.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 6055 from 6603 to get 548.
Bring next digit (9) of the dividend behind the 548 and repeat the process: 5489 / 865

Step 6:
865 goes into 5489 6 times with a remainder of 299.
Write down 6 as next digit of the result. 
Result so far: 976.0
The remainder is 299 after subtracting 5190 from 5489.
Bring next digit (8) of the dividend behind the 299 and repeat the process: 2998 / 865

Moving on to step 7:
2998 divided by 865 is 3 with a remainder of 403.
Record the quotient 3 as the next digit in the result. 
Result so far: 9763.0
If we take 2595 away from 2998, we end up with 403.
Fetch the next digit (7) from the dividend, attach it to 403 and continue: 4037 / 865

Moving on to step 8:
The number 865 fits into 4037 4 times, leaving a remainder of 577.
The number 4 becomes the next digit in our result. 
Result so far: 97634.0
If we subtract 3460 from 4037, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 9:
When dividing 5770 by 865, we get 6 with a remainder of 580.
Record the quotient 6 as the next digit in the result. 
Result so far: 97634.6
Subtracting 5190 from 5770 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 10:
5800 divided by 865 is 6 with a remainder of 610.
Use 6 as the next digit of our solution. 
Result so far: 97634.66
Subtract 5190 from 5800 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

After the division, we end up with 97634.66 and a remainder of 0.61.
