We look at the division of 65270221 by 823 
The aim is to understand the frequency of 823 in 65270221.

Advancing to step 1:
When dividing 6 by 823, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 823

Step 2:
When dividing 65 by 823, we get 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 823

Going ahead to step 3:
If we divide 652 by 823, we get 0 and a remainder of 652.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 652, we end up with 652.
Take the next digit (7) from the dividend and append it to 652, then repeat: 6527 / 823

Let's proceed to step 4:
If we divide 6527 by 823, we get 7 and a remainder of 766.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5761 from 6527, we get 766.
Append the next digit (0) from the dividend to 766 and continue with: 7660 / 823

Going ahead to step 5:
The number 823 fits into 7660 9 times, leaving a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 7407 from 7660, we get 253.
Bring next digit (2) of the dividend behind the 253 and repeat the process: 2532 / 823

Going ahead to step 6:
If we divide 2532 by 823, we get 3 and a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 793.0
If we take 2469 away from 2532, we end up with 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 823

Let's proceed to step 7:
If we divide 632 by 823, we get 0 and a remainder of 632.
Use 0 as the next digit of our solution. 
Result so far: 7930.0
Deduct 0 from 632 and we're left with 632.
Fetch the next digit (1) from the dividend, attach it to 632 and continue: 6321 / 823

On to step 8:
If we divide 6321 by 823, we get 7 and a remainder of 560.
The next digit of our result is 7. 
Result so far: 79307.0
Subtracting 5761 from 6321 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 9:
823 can be fit into 5600 6 times, resulting in a remainder of 662.
Put 6 as the next digit of the answer. 
Result so far: 79307.6
If we subtract 4938 from 5600, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 10:
823 goes into 6620 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 79307.68
If we subtract 6584 from 6620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 823 is 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 79307.68
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
The number 823 fits into 3600 4 times, leaving a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 79307.6804
The remainder is 308 after subtracting 3292 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 13:
If we divide 3080 by 823, we get 3 and a remainder of 611.
The next digit of our result is 3. 
Result so far: 79307.68043
Subtracting 2469 from 3080 leaves us with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Advancing to step 14:
823 can be fit into 6110 7 times, resulting in a remainder of 349.
Put 7 as the next digit of the answer. 
Result so far: 79307.680437
If we take 5761 away from 6110, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 15:
823 can be fit into 3490 4 times, resulting in a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 79307.6804374
If we take 3292 away from 3490, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 16:
823 can be fit into 1980 2 times, resulting in a remainder of 334.
Write down 2 as next digit of the result. 
Result so far: 79307.68043742
The remainder is 334 after subtracting 1646 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The quotient of the division is 79307.68043742, and the remainder is 3.34e-07.
