We look at the division of 32570301 by 518 
The aim is to understand the frequency of 518 in 32570301.

Advancing to step 1:
3 divided by 518 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 518

Let's proceed to step 2:
When dividing 32 by 518, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 518

Let's proceed to step 3:
518 can be fit into 325 0 times, resulting in a remainder of 325.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 325 after subtracting 0 from 325.
Grab the next digit (7) from the dividend, add it to 325, then carry on: 3257 / 518

Let's proceed to step 4:
If we divide 3257 by 518, we get 6 and a remainder of 149.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 149 after subtracting 3108 from 3257.
Bring next digit (0) of the dividend behind the 149 and repeat the process: 1490 / 518

Step 5:
518 can be fit into 1490 2 times, resulting in a remainder of 454.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 1036 from 1490 and we're left with 454.
Include the next digit (3) from the dividend after 454, then repeat: 4543 / 518

Advancing to step 6:
The number 518 fits into 4543 8 times, leaving a remainder of 399.
The number 8 becomes the next digit in our result. 
Result so far: 628.0
Subtract 4144 from 4543 to get 399.
Take the next digit (0) from the dividend and append it to 399, then repeat: 3990 / 518

Moving on to step 7:
When dividing 3990 by 518, we get 7 with a remainder of 364.
Write down 7 as next digit of the result. 
Result so far: 6287.0
If we subtract 3626 from 3990, we get 364.
Append the next digit (1) from the dividend to 364 and continue with: 3641 / 518

Step 8:
When dividing 3641 by 518, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 62877.0
Subtract 3626 from 3641 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 518 is 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 62877.0
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
1500 divided by 518 is 2 with a remainder of 464.
Put 2 as the next digit of the answer. 
Result so far: 62877.02
Deduct 1036 from 1500 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 11:
4640 divided by 518 is 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 62877.028
Subtracting 4144 from 4640 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 12:
518 can be fit into 4960 9 times, resulting in a remainder of 298.
Use 9 as the next digit of our solution. 
Result so far: 62877.0289
Subtracting 4662 from 4960 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 13:
If we divide 2980 by 518, we get 5 and a remainder of 390.
The next digit of our result is 5. 
Result so far: 62877.02895
If we take 2590 away from 2980, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 14:
3900 divided by 518 is 7 with a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 62877.028957
If we take 3626 away from 3900, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 15:
2740 divided by 518 is 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 62877.0289575
Deduct 2590 from 2740 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
The number 518 fits into 1500 2 times, leaving a remainder of 464.
Use 2 as the next digit of our solution. 
Result so far: 62877.02895752
Subtract 1036 from 1500 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

After the division, we end up with 62877.02895752 and a remainder of 4.64e-07.
