52998219 ÷ 805 
The aim is to understand the frequency of 805 in 52998219.

Step 1:
When dividing 5 by 805, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 805

Advancing to step 2:
The number 805 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 805

Step 3:
When dividing 529 by 805, we get 0 with a remainder of 529.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 529, we end up with 529.
Append the next digit (9) from the dividend to 529 and continue with: 5299 / 805

On to step 4:
If we divide 5299 by 805, we get 6 and a remainder of 469.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4830 from 5299, we get 469.
Grab the next digit (8) from the dividend, add it to 469, then carry on: 4698 / 805

Advancing to step 5:
4698 divided by 805 is 5 with a remainder of 673.
The next digit of our result is 5. 
Result so far: 65.0
If we take 4025 away from 4698, we end up with 673.
Append the next digit (2) from the dividend to 673 and continue with: 6732 / 805

Going ahead to step 6:
When dividing 6732 by 805, we get 8 with a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 658.0
If we take 6440 away from 6732, we end up with 292.
Grab the next digit (1) from the dividend, add it to 292, then carry on: 2921 / 805

Step 7:
805 goes into 2921 3 times with a remainder of 506.
Put 3 as the next digit of the answer. 
Result so far: 6583.0
Subtract 2415 from 2921 to get 506.
Append the next digit (9) from the dividend to 506 and continue with: 5069 / 805

Advancing to step 8:
If we divide 5069 by 805, we get 6 and a remainder of 239.
The number 6 becomes the next digit in our result. 
Result so far: 65836.0
Subtracting 4830 from 5069 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 9:
When dividing 2390 by 805, we get 2 with a remainder of 780.
Put 2 as the next digit of the answer. 
Result so far: 65836.2
Subtracting 1610 from 2390 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 10:
If we divide 7800 by 805, we get 9 and a remainder of 555.
The number 9 becomes the next digit in our result. 
Result so far: 65836.29
Subtract 7245 from 7800 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Step 11:
If we divide 5550 by 805, we get 6 and a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 65836.296
Deduct 4830 from 5550 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 12:
805 goes into 7200 8 times with a remainder of 760.
The number 8 becomes the next digit in our result. 
Result so far: 65836.2968
The remainder is 760 after subtracting 6440 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 13:
When dividing 7600 by 805, we get 9 with a remainder of 355.
Put 9 as the next digit of the answer. 
Result so far: 65836.29689
If we take 7245 away from 7600, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 14:
805 goes into 3550 4 times with a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 65836.296894
Deduct 3220 from 3550 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 15:
805 can be fit into 3300 4 times, resulting in a remainder of 80.
The next digit of our result is 4. 
Result so far: 65836.2968944
Subtract 3220 from 3300 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 65836.2968944 with a remainder of 8e-07.
