957995 ÷ 13 
The aim is to understand the frequency of 13 in 957995.

Going ahead to step 1:
9 divided by 13 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 13

Let's proceed to step 2:
If we divide 95 by 13, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 91 from 95 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 13

Moving on to step 3:
13 can be fit into 47 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 39 from 47 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 13

Step 4:
13 goes into 89 6 times with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 736.0
Subtract 78 from 89 to get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 13

Moving on to step 5:
The number 13 fits into 119 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 7369.0
If we subtract 117 from 119, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 13

Going ahead to step 6:
When dividing 25 by 13, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 73691.0
Subtract 13 from 25 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.

Step 7:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 73691.9
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 8:
When dividing 30 by 13, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 73691.92
If we take 26 away from 30, 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.

On to step 9:
40 divided by 13 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 73691.923
Subtract 39 from 40 to 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.

Advancing to step 10:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 73691.923
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.

Step 11:
When dividing 100 by 13, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 73691.92307
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.

Step 12:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 73691.923076
Deduct 78 from 90 and we're left 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.

Let's proceed to step 13:
13 goes into 120 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 73691.9230769
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:
30 divided by 13 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 73691.92307692
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.

In conclusion, the division gives 73691.92307692 with a balance of 4e-09.
