We look at the division of 38258664 by 823 
The aim is to understand the frequency of 823 in 38258664.

Advancing to step 1:
823 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 823

On to step 2:
If we divide 38 by 823, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 823

Let's proceed to step 3:
When dividing 382 by 823, we get 0 with a remainder of 382.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 382 leaves us with 382.
Take the next digit (5) from the dividend and append it to 382, then repeat: 3825 / 823

Step 4:
823 can be fit into 3825 4 times, resulting in a remainder of 533.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3292 from 3825 and we're left with 533.
Bring next digit (8) of the dividend behind the 533 and repeat the process: 5338 / 823

Moving on to step 5:
If we divide 5338 by 823, we get 6 and a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 4938 away from 5338, we end up with 400.
Fetch the next digit (6) from the dividend, attach it to 400 and continue: 4006 / 823

Let's proceed to step 6:
823 goes into 4006 4 times with a remainder of 714.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
If we subtract 3292 from 4006, we get 714.
Include the next digit (6) from the dividend after 714, then repeat: 7146 / 823

Advancing to step 7:
823 goes into 7146 8 times with a remainder of 562.
Write down 8 as next digit of the result. 
Result so far: 4648.0
Subtract 6584 from 7146 to get 562.
Fetch the next digit (4) from the dividend, attach it to 562 and continue: 5624 / 823

Let's proceed to step 8:
The number 823 fits into 5624 6 times, leaving a remainder of 686.
Use 6 as the next digit of our solution. 
Result so far: 46486.0
Deduct 4938 from 5624 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 9:
823 can be fit into 6860 8 times, resulting in a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 46486.8
Deduct 6584 from 6860 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 10:
823 goes into 2760 3 times with a remainder of 291.
Put 3 as the next digit of the answer. 
Result so far: 46486.83
Subtract 2469 from 2760 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 11:
2910 divided by 823 is 3 with a remainder of 441.
Record the quotient 3 as the next digit in the result. 
Result so far: 46486.833
Subtract 2469 from 2910 to get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

The final outcome is 46486.833, with a leftover of 0.0441.
