Let's divide 973962 by 13
The aim is to understand the frequency of 13 in 973962.

Let's proceed to step 1:
If we divide 9 by 13, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 13

Moving on to step 2:
The number 13 fits into 97 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 91 from 97 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 13

Advancing to step 3:
The number 13 fits into 63 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 52 from 63 and we're left with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 13

Going ahead to step 4:
13 can be fit into 119 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 749.0
Subtract 117 from 119 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 13

Step 5:
26 divided by 13 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7492.0
If we take 26 away from 26, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 13

Let's proceed to step 6:
13 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 74920.0
Subtracting 0 from 2 leaves us 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.

On to step 7:
When dividing 20 by 13, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 74920.1
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.

On to step 8:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 74920.15
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.

Advancing to step 9:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 74920.153
If we subtract 39 from 50, we 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 10:
When dividing 110 by 13, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 74920.1538
Subtract 104 from 110 to 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.

Let's proceed to step 11:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 74920.15384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 74920.153846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
When dividing 20 by 13, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 74920.1538461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 74920.15384615
Deduct 65 from 70 and we're left 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.

The final result is 74920.15384615 with a remainder of 5e-09.
