Let's divide 25498812 by 649
The aim is to understand the frequency of 649 in 25498812.

Let's proceed to step 1:
2 divided by 649 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 649

Going ahead to step 2:
When dividing 25 by 649, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 649

On to step 3:
When dividing 254 by 649, we get 0 with a remainder of 254.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 254, we end up with 254.
Bring next digit (9) of the dividend behind the 254 and repeat the process: 2549 / 649

Moving on to step 4:
649 goes into 2549 3 times with a remainder of 602.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1947 away from 2549, we end up with 602.
Bring next digit (8) of the dividend behind the 602 and repeat the process: 6028 / 649

Step 5:
649 can be fit into 6028 9 times, resulting in a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 187 after subtracting 5841 from 6028.
Include the next digit (8) from the dividend after 187, then repeat: 1878 / 649

Moving on to step 6:
When dividing 1878 by 649, we get 2 with a remainder of 580.
Write down 2 as next digit of the result. 
Result so far: 392.0
If we take 1298 away from 1878, we end up with 580.
Fetch the next digit (1) from the dividend, attach it to 580 and continue: 5801 / 649

On to step 7:
The number 649 fits into 5801 8 times, leaving a remainder of 609.
Put 8 as the next digit of the answer. 
Result so far: 3928.0
If we take 5192 away from 5801, we end up with 609.
Include the next digit (2) from the dividend after 609, then repeat: 6092 / 649

Advancing to step 8:
649 goes into 6092 9 times with a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 39289.0
If we subtract 5841 from 6092, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 9:
649 can be fit into 2510 3 times, resulting in a remainder of 563.
The next digit of our result is 3. 
Result so far: 39289.3
The remainder is 563 after subtracting 1947 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Step 10:
649 goes into 5630 8 times with a remainder of 438.
Put 8 as the next digit of the answer. 
Result so far: 39289.38
If we subtract 5192 from 5630, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 11:
If we divide 4380 by 649, we get 6 and a remainder of 486.
Record the quotient 6 as the next digit in the result. 
Result so far: 39289.386
Subtracting 3894 from 4380 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 12:
649 can be fit into 4860 7 times, resulting in a remainder of 317.
The number 7 becomes the next digit in our result. 
Result so far: 39289.3867
Subtracting 4543 from 4860 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 13:
The number 649 fits into 3170 4 times, leaving a remainder of 574.
The next digit of our result is 4. 
Result so far: 39289.38674
Subtract 2596 from 3170 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 14:
5740 divided by 649 is 8 with a remainder of 548.
Write down 8 as next digit of the result. 
Result so far: 39289.386748
If we take 5192 away from 5740, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 15:
649 goes into 5480 8 times with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 39289.3867488
Subtracting 5192 from 5480 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 39289.3867488 with a remaining 2.88e-06.
