823952 divided by 13 
The aim is to understand the frequency of 13 in 823952.

Advancing to step 1:
13 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 13

Let's proceed to step 2:
The number 13 fits into 82 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 78 away from 82, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 13

Advancing to step 3:
43 divided by 13 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 39 from 43 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 13

Going ahead to step 4:
If we divide 49 by 13, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 633.0
If we take 39 away from 49, we end up with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 13

Moving on to step 5:
When dividing 105 by 13, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 6338.0
Deduct 104 from 105 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 13

On to step 6:
12 divided by 13 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 63380.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 63380.9
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 63380.92
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
13 goes into 40 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 63380.923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
When dividing 10 by 13, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 63380.923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
The number 13 fits into 100 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 63380.92307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 63380.923076
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
13 goes into 120 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 63380.9230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
If we divide 30 by 13, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 63380.92307692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 63380.92307692 and a remainder of 4e-09.
