We look at the division of 13306620 by 649 
The aim is to understand the frequency of 649 in 13306620.

Moving on to step 1:
If we divide 1 by 649, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 649

Advancing to step 2:
13 divided by 649 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 649

Going ahead to step 3:
649 can be fit into 133 0 times, resulting in a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 133 after subtracting 0 from 133.
Bring next digit (0) of the dividend behind the 133 and repeat the process: 1330 / 649

Advancing to step 4:
If we divide 1330 by 649, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1298 from 1330 to get 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 649

Advancing to step 5:
When dividing 326 by 649, we get 0 with a remainder of 326.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 326, we end up with 326.
Fetch the next digit (6) from the dividend, attach it to 326 and continue: 3266 / 649

Moving on to step 6:
The number 649 fits into 3266 5 times, leaving a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 205.0
If we take 3245 away from 3266, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 649

Step 7:
649 goes into 212 0 times with a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 2050.0
Deduct 0 from 212 and we're left with 212.
Bring next digit (0) of the dividend behind the 212 and repeat the process: 2120 / 649

Let's proceed to step 8:
If we divide 2120 by 649, we get 3 and a remainder of 173.
The next digit of our result is 3. 
Result so far: 20503.0
Subtract 1947 from 2120 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 9:
If we divide 1730 by 649, we get 2 and a remainder of 432.
Write down 2 as next digit of the result. 
Result so far: 20503.2
Deduct 1298 from 1730 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 10:
When dividing 4320 by 649, we get 6 with a remainder of 426.
Record the quotient 6 as the next digit in the result. 
Result so far: 20503.26
If we take 3894 away from 4320, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 11:
649 goes into 4260 6 times with a remainder of 366.
Put 6 as the next digit of the answer. 
Result so far: 20503.266
If we take 3894 away from 4260, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

In conclusion, the division gives 20503.266 with a balance of 0.0366.
