We divide 649460 by 13
The aim is to understand the frequency of 13 in 649460.

Going ahead to step 1:
The number 13 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 13

Moving on to step 2:
13 can be fit into 64 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 52 from 64 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 13

On to step 3:
If we divide 129 by 13, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 117 from 129 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 13

On to step 4:
13 goes into 124 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
Deduct 117 from 124 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 13

On to step 5:
The number 13 fits into 76 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 4995.0
Deduct 65 from 76 and we're left with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 13

Going ahead to step 6:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 49958.0
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 13, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 49958.4
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.

Let's proceed to step 8:
13 goes into 80 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 49958.46
Subtract 78 from 80 to 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.

On to step 9:
When dividing 20 by 13, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 49958.461
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.

Step 10:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 49958.4615
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.

Advancing to step 11:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 49958.46153
Subtracting 39 from 50 leaves us 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.

On to step 12:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 49958.461538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
When dividing 60 by 13, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 49958.4615384
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.

Going ahead to step 14:
When dividing 80 by 13, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 49958.46153846
Subtract 78 from 80 to 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.

Our division results in 49958.46153846 with a remaining 2e-09.
