We look at the division of 20995450 by 649 
The aim is to understand the frequency of 649 in 20995450.

Moving on to step 1:
When dividing 2 by 649, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 649

Moving on to step 2:
649 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 649

Advancing to step 3:
209 divided by 649 is 0 with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 649

Going ahead to step 4:
When dividing 2099 by 649, we get 3 with a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1947 from 2099 leaves us with 152.
Append the next digit (5) from the dividend to 152 and continue with: 1525 / 649

Advancing to step 5:
The number 649 fits into 1525 2 times, leaving a remainder of 227.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 1298 from 1525 and we're left with 227.
Take the next digit (4) from the dividend and append it to 227, then repeat: 2274 / 649

Advancing to step 6:
If we divide 2274 by 649, we get 3 and a remainder of 327.
Put 3 as the next digit of the answer. 
Result so far: 323.0
Subtracting 1947 from 2274 leaves us with 327.
Include the next digit (5) from the dividend after 327, then repeat: 3275 / 649

Let's proceed to step 7:
If we divide 3275 by 649, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3235.0
Subtracting 3245 from 3275 leaves us with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 649

Let's proceed to step 8:
If we divide 300 by 649, we get 0 and a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 32350.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 9:
The number 649 fits into 3000 4 times, leaving a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 32350.4
Subtracting 2596 from 3000 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 10:
649 can be fit into 4040 6 times, resulting in a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 32350.46
Deduct 3894 from 4040 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 11:
649 can be fit into 1460 2 times, resulting in a remainder of 162.
Use 2 as the next digit of our solution. 
Result so far: 32350.462
If we take 1298 away from 1460, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 12:
The number 649 fits into 1620 2 times, leaving a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 32350.4622
Deduct 1298 from 1620 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The final result is 32350.4622 with a remainder of 0.00322.
