We're dividing 66002969 by 823 
The aim is to understand the frequency of 823 in 66002969.

Let's proceed to step 1:
823 can be fit into 6 0 times, resulting in 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 823

Advancing to step 2:
If we divide 66 by 823, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 823

On to step 3:
823 can be fit into 660 0 times, resulting in a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 660 after subtracting 0 from 660.
Include the next digit (0) from the dividend after 660, then repeat: 6600 / 823

Moving on to step 4:
The number 823 fits into 6600 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6584 from 6600, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 823

Advancing to step 5:
When dividing 162 by 823, we get 0 with a remainder of 162.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 162, we end up with 162.
Append the next digit (9) from the dividend to 162 and continue with: 1629 / 823

Moving on to step 6:
1629 divided by 823 is 1 with a remainder of 806.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
The remainder is 806 after subtracting 823 from 1629.
Append the next digit (6) from the dividend to 806 and continue with: 8066 / 823

Moving on to step 7:
When dividing 8066 by 823, we get 9 with a remainder of 659.
Use 9 as the next digit of our solution. 
Result so far: 8019.0
If we subtract 7407 from 8066, we get 659.
Include the next digit (9) from the dividend after 659, then repeat: 6599 / 823

Let's proceed to step 8:
If we divide 6599 by 823, we get 8 and a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 80198.0
If we subtract 6584 from 6599, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 823, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 80198.0
Deduct 0 from 150 and we're left 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 10:
823 goes into 1500 1 times with a remainder of 677.
Use 1 as the next digit of our solution. 
Result so far: 80198.01
The remainder is 677 after subtracting 823 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Moving on to step 11:
The number 823 fits into 6770 8 times, leaving a remainder of 186.
The next digit of our result is 8. 
Result so far: 80198.018
If we take 6584 away from 6770, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 12:
1860 divided by 823 is 2 with a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 80198.0182
Deduct 1646 from 1860 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 13:
823 can be fit into 2140 2 times, resulting in a remainder of 494.
The number 2 becomes the next digit in our result. 
Result so far: 80198.01822
If we subtract 1646 from 2140, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Our division results in 80198.01822 with a remaining 0.000494.
