We look at the division of 77594566 by 865 
The aim is to understand the frequency of 865 in 77594566.

Going ahead to step 1:
865 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 865

Step 2:
The number 865 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 865

Moving on to step 3:
The number 865 fits into 775 0 times, leaving a remainder of 775.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 775, we get 775.
Include the next digit (9) from the dividend after 775, then repeat: 7759 / 865

On to step 4:
7759 divided by 865 is 8 with a remainder of 839.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6920 from 7759 and we're left with 839.
Append the next digit (4) from the dividend to 839 and continue with: 8394 / 865

On to step 5:
When dividing 8394 by 865, we get 9 with a remainder of 609.
Put 9 as the next digit of the answer. 
Result so far: 89.0
The remainder is 609 after subtracting 7785 from 8394.
Grab the next digit (5) from the dividend, add it to 609, then carry on: 6095 / 865

Advancing to step 6:
The number 865 fits into 6095 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 897.0
Subtracting 6055 from 6095 leaves us with 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 865

Step 7:
When dividing 406 by 865, we get 0 with a remainder of 406.
Write down 0 as next digit of the result. 
Result so far: 8970.0
Subtract 0 from 406 to get 406.
Include the next digit (6) from the dividend after 406, then repeat: 4066 / 865

On to step 8:
If we divide 4066 by 865, we get 4 and a remainder of 606.
The number 4 becomes the next digit in our result. 
Result so far: 89704.0
Subtract 3460 from 4066 to get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 9:
When dividing 6060 by 865, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 89704.7
The remainder is 5 after subtracting 6055 from 6060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
If we divide 50 by 865, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 89704.7
Subtracting 0 from 50 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.

Moving on to step 11:
The number 865 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 89704.7
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 89704.7 with a remainder of 0.05.
