26293639 divided by 638 
The aim is to understand the frequency of 638 in 26293639.

Step 1:
638 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 638

Step 2:
26 divided by 638 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 638

Going ahead to step 3:
262 divided by 638 is 0 with a remainder of 262.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 262 leaves us with 262.
Bring next digit (9) of the dividend behind the 262 and repeat the process: 2629 / 638

Let's proceed to step 4:
2629 divided by 638 is 4 with a remainder of 77.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2552 from 2629 to get 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 638

Let's proceed to step 5:
773 divided by 638 is 1 with a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 638 from 773 leaves us with 135.
Fetch the next digit (6) from the dividend, attach it to 135 and continue: 1356 / 638

Moving on to step 6:
The number 638 fits into 1356 2 times, leaving a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 412.0
Deduct 1276 from 1356 and we're left with 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 638

Step 7:
If we divide 803 by 638, we get 1 and a remainder of 165.
Put 1 as the next digit of the answer. 
Result so far: 4121.0
Subtracting 638 from 803 leaves us with 165.
Grab the next digit (9) from the dividend, add it to 165, then carry on: 1659 / 638

Going ahead to step 8:
638 goes into 1659 2 times with a remainder of 383.
Use 2 as the next digit of our solution. 
Result so far: 41212.0
Deduct 1276 from 1659 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Step 9:
The number 638 fits into 3830 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 41212.6
If we take 3828 away from 3830, 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.

Advancing to step 10:
638 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 41212.6
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 638, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 41212.6
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 41212.6 with a balance of 0.02.
