41519190 divided by 638 
The aim is to understand the frequency of 638 in 41519190.

Moving on to step 1:
When dividing 4 by 638, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 638

On to step 2:
The number 638 fits into 41 0 times, leaving a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 638

Moving on to step 3:
415 divided by 638 is 0 with a remainder of 415.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 415 after subtracting 0 from 415.
Bring next digit (1) of the dividend behind the 415 and repeat the process: 4151 / 638

On to step 4:
The number 638 fits into 4151 6 times, leaving a remainder of 323.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 323 after subtracting 3828 from 4151.
Include the next digit (9) from the dividend after 323, then repeat: 3239 / 638

Moving on to step 5:
When dividing 3239 by 638, we get 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 49 after subtracting 3190 from 3239.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 638

Moving on to step 6:
When dividing 491 by 638, we get 0 with a remainder of 491.
Write down 0 as next digit of the result. 
Result so far: 650.0
Subtract 0 from 491 to get 491.
Take the next digit (9) from the dividend and append it to 491, then repeat: 4919 / 638

Let's proceed to step 7:
4919 divided by 638 is 7 with a remainder of 453.
Record the quotient 7 as the next digit in the result. 
Result so far: 6507.0
If we subtract 4466 from 4919, we get 453.
Append the next digit (0) from the dividend to 453 and continue with: 4530 / 638

Advancing to step 8:
If we divide 4530 by 638, we get 7 and a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 65077.0
If we subtract 4466 from 4530, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
638 goes into 640 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 65077.1
Deduct 638 from 640 and we're left 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.

Let's proceed to step 10:
When dividing 20 by 638, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 65077.1
Subtracting 0 from 20 leaves us with 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:
638 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 65077.1
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 65077.1 and a remainder of 0.02.
