We divide 826531 by 13
The aim is to understand the frequency of 13 in 826531.

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
Subtracting 0 from 8 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 13

Moving on to step 2:
13 goes into 82 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 78 away from 82, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 13

Advancing to step 3:
The number 13 fits into 46 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 39 from 46 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 13

Let's proceed to step 4:
13 goes into 75 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 635.0
The remainder is 10 after subtracting 65 from 75.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 13

Step 5:
When dividing 103 by 13, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 6357.0
If we subtract 91 from 103, we get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 13

On to step 6:
If we divide 121 by 13, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 63579.0
If we take 117 away from 121, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 13, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 63579.3
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 63579.3
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 63579.307
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.

On to step 10:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 63579.3076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
13 goes into 120 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 63579.30769
Subtracting 117 from 120 leaves us 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.

Let's proceed to step 12:
13 goes into 30 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 63579.307692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 13, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 63579.3076923
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
When dividing 10 by 13, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 63579.3076923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 63579.3076923 with a remainder of 1e-08.
