We're dividing 65164095 by 805 
The aim is to understand the frequency of 805 in 65164095.

Going ahead to step 1:
If we divide 6 by 805, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 805

Moving on to step 2:
If we divide 65 by 805, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 805

Going ahead to step 3:
805 goes into 651 0 times with a remainder of 651.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 651 and we're left with 651.
Bring next digit (6) of the dividend behind the 651 and repeat the process: 6516 / 805

Moving on to step 4:
6516 divided by 805 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6440 from 6516, we get 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 805

Going ahead to step 5:
764 divided by 805 is 0 with a remainder of 764.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtract 0 from 764 to get 764.
Bring next digit (0) of the dividend behind the 764 and repeat the process: 7640 / 805

Going ahead to step 6:
If we divide 7640 by 805, we get 9 and a remainder of 395.
Write down 9 as next digit of the result. 
Result so far: 809.0
If we subtract 7245 from 7640, we get 395.
Grab the next digit (9) from the dividend, add it to 395, then carry on: 3959 / 805

Let's proceed to step 7:
When dividing 3959 by 805, we get 4 with a remainder of 739.
Use 4 as the next digit of our solution. 
Result so far: 8094.0
Subtract 3220 from 3959 to get 739.
Append the next digit (5) from the dividend to 739 and continue with: 7395 / 805

Advancing to step 8:
If we divide 7395 by 805, we get 9 and a remainder of 150.
Write down 9 as next digit of the result. 
Result so far: 80949.0
Subtracting 7245 from 7395 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
The number 805 fits into 1500 1 times, leaving a remainder of 695.
Put 1 as the next digit of the answer. 
Result so far: 80949.1
Deduct 805 from 1500 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Going ahead to step 10:
When dividing 6950 by 805, we get 8 with a remainder of 510.
The number 8 becomes the next digit in our result. 
Result so far: 80949.18
The remainder is 510 after subtracting 6440 from 6950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 11:
The number 805 fits into 5100 6 times, leaving a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 80949.186
Subtracting 4830 from 5100 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
If we divide 2700 by 805, we get 3 and a remainder of 285.
The next digit of our result is 3. 
Result so far: 80949.1863
Subtract 2415 from 2700 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 13:
805 can be fit into 2850 3 times, resulting in a remainder of 435.
Record the quotient 3 as the next digit in the result. 
Result so far: 80949.18633
If we subtract 2415 from 2850, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

After the division, we end up with 80949.18633 and a remainder of 0.000435.
