958812 divided by 13 
The aim is to understand the frequency of 13 in 958812.

Let's proceed to step 1:
When dividing 9 by 13, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 13

Going ahead to step 2:
13 goes into 95 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 91 from 95, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 13

Let's proceed to step 3:
The number 13 fits into 48 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 39 from 48 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 13

Step 4:
If we divide 98 by 13, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 737.0
Deduct 91 from 98 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 13

On to step 5:
13 goes into 71 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 7375.0
The remainder is 6 after subtracting 65 from 71.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 13

Moving on to step 6:
If we divide 62 by 13, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 73754.0
Subtract 52 from 62 to 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.

Let's proceed to step 7:
If we divide 100 by 13, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 73754.7
If we subtract 91 from 100, we get 9.
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 8:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 73754.76
If we subtract 78 from 90, we 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.

Step 9:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 73754.769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
When dividing 30 by 13, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 73754.7692
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.

Going ahead to step 11:
If we divide 40 by 13, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 73754.76923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
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: 73754.76923
Subtract 0 from 10 to 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.

Going ahead to step 13:
13 goes into 100 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 73754.7692307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
If we divide 90 by 13, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 73754.76923076
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.

The quotient of the division is 73754.76923076, and the remainder is 1.2e-08.
