We look at the division of 65245456 by 823 
The aim is to understand the frequency of 823 in 65245456.

Moving on to step 1:
823 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 823

Going ahead to step 2:
If we divide 65 by 823, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 823

Advancing to step 3:
If we divide 652 by 823, we get 0 and a remainder of 652.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 652 and we're left with 652.
Take the next digit (4) from the dividend and append it to 652, then repeat: 6524 / 823

Let's proceed to step 4:
When dividing 6524 by 823, we get 7 with a remainder of 763.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 763 after subtracting 5761 from 6524.
Append the next digit (5) from the dividend to 763 and continue with: 7635 / 823

Let's proceed to step 5:
The number 823 fits into 7635 9 times, leaving a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 7407 from 7635 and we're left with 228.
Bring next digit (4) of the dividend behind the 228 and repeat the process: 2284 / 823

On to step 6:
If we divide 2284 by 823, we get 2 and a remainder of 638.
Use 2 as the next digit of our solution. 
Result so far: 792.0
Deduct 1646 from 2284 and we're left with 638.
Include the next digit (5) from the dividend after 638, then repeat: 6385 / 823

Advancing to step 7:
The number 823 fits into 6385 7 times, leaving a remainder of 624.
Use 7 as the next digit of our solution. 
Result so far: 7927.0
If we take 5761 away from 6385, we end up with 624.
Include the next digit (6) from the dividend after 624, then repeat: 6246 / 823

Going ahead to step 8:
823 can be fit into 6246 7 times, resulting in a remainder of 485.
Record the quotient 7 as the next digit in the result. 
Result so far: 79277.0
The remainder is 485 after subtracting 5761 from 6246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 9:
823 can be fit into 4850 5 times, resulting in a remainder of 735.
Record the quotient 5 as the next digit in the result. 
Result so far: 79277.5
Deduct 4115 from 4850 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 10:
The number 823 fits into 7350 8 times, leaving a remainder of 766.
The number 8 becomes the next digit in our result. 
Result so far: 79277.58
The remainder is 766 after subtracting 6584 from 7350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Step 11:
If we divide 7660 by 823, we get 9 and a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 79277.589
Subtract 7407 from 7660 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 12:
2530 divided by 823 is 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 79277.5893
Subtract 2469 from 2530 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 13:
The number 823 fits into 610 0 times, leaving a remainder of 610.
Write down 0 as next digit of the result. 
Result so far: 79277.5893
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 14:
6100 divided by 823 is 7 with a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 79277.589307
If we take 5761 away from 6100, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 15:
823 can be fit into 3390 4 times, resulting in a remainder of 98.
The next digit of our result is 4. 
Result so far: 79277.5893074
If we take 3292 away from 3390, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
The number 823 fits into 980 1 times, leaving a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 79277.58930741
If we take 823 away from 980, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Our division results in 79277.58930741 with a remaining 1.57e-07.
