Let's divide 953986 by 13
The aim is to understand the frequency of 13 in 953986.

Going ahead to step 1:
13 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 13

Let's proceed to step 2:
95 divided by 13 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 91 from 95 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 13

Advancing to step 3:
If we divide 43 by 13, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtract 39 from 43 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 13

Going ahead to step 4:
When dividing 49 by 13, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.0
Subtract 39 from 49 to get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 13

Let's proceed to step 5:
13 goes into 108 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 7338.0
The remainder is 4 after subtracting 104 from 108.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 13

Moving on to step 6:
When dividing 46 by 13, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 73383.0
If we take 39 away from 46, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 13, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 73383.5
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 13 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 73383.53
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 73383.538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 73383.5384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 13, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 73383.53846
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
20 divided by 13 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 73383.538461
Deduct 13 from 20 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
13 goes into 70 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 73383.5384615
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
When dividing 50 by 13, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 73383.53846153
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 73383.53846153 with a remainder of 1.1e-08.
