We divide 42506103 by 518
The aim is to understand the frequency of 518 in 42506103.

Going ahead to step 1:
518 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 518

Advancing to step 2:
42 divided by 518 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 518

Step 3:
If we divide 425 by 518, we get 0 and a remainder of 425.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Bring next digit (0) of the dividend behind the 425 and repeat the process: 4250 / 518

On to step 4:
If we divide 4250 by 518, we get 8 and a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 4144 from 4250 leaves us with 106.
Bring next digit (6) of the dividend behind the 106 and repeat the process: 1066 / 518

Going ahead to step 5:
If we divide 1066 by 518, we get 2 and a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 1036 from 1066 leaves us with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 518

Let's proceed to step 6:
The number 518 fits into 301 0 times, leaving a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 820.0
If we subtract 0 from 301, we get 301.
Grab the next digit (0) from the dividend, add it to 301, then carry on: 3010 / 518

Moving on to step 7:
When dividing 3010 by 518, we get 5 with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 8205.0
If we take 2590 away from 3010, we end up with 420.
Include the next digit (3) from the dividend after 420, then repeat: 4203 / 518

Going ahead to step 8:
When dividing 4203 by 518, we get 8 with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 82058.0
Subtract 4144 from 4203 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
518 can be fit into 590 1 times, resulting in a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 82058.1
Subtracting 518 from 590 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
518 goes into 720 1 times with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 82058.11
Subtract 518 from 720 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

After the division, we end up with 82058.11 and a remainder of 0.202.
