We divide 649837 by 13
The aim is to understand the frequency of 13 in 649837.

Let's proceed to step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 13

Step 2:
The number 13 fits into 64 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 52 from 64 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 13

Let's proceed to step 3:
If we divide 129 by 13, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 117 from 129 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 13

Moving on to step 4:
13 goes into 128 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
If we subtract 117 from 128, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 13

Step 5:
If we divide 113 by 13, we get 8 and a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 4998.0
Deduct 104 from 113 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 13

Step 6:
When dividing 97 by 13, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 49987.0
Subtracting 91 from 97 leaves us with 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 7:
60 divided by 13 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 49987.4
The remainder is 8 after subtracting 52 from 60.
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 8:
When dividing 80 by 13, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 49987.46
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.

Let's proceed to step 9:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 49987.461
Subtract 13 from 20 to 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.

On to step 10:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 49987.4615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 49987.46153
The remainder is 11 after subtracting 39 from 50.
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 12:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 49987.461538
If we take 104 away from 110, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 49987.4615384
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.

Advancing to step 14:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 49987.46153846
If we take 78 away from 80, we end up 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.

The final result is 49987.46153846 with a remainder of 2e-09.
