We look at the division of 52169264 by 518 
The aim is to understand the frequency of 518 in 52169264.

Let's proceed to step 1:
When dividing 5 by 518, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 518

Moving on to step 2:
When dividing 52 by 518, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 518

On to step 3:
The number 518 fits into 521 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 518 from 521 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 518

Going ahead to step 4:
If we divide 36 by 518, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 518

Advancing to step 5:
369 divided by 518 is 0 with a remainder of 369.
The next digit of our result is 0. 
Result so far: 100.0
Subtract 0 from 369 to get 369.
Include the next digit (2) from the dividend after 369, then repeat: 3692 / 518

Let's proceed to step 6:
518 can be fit into 3692 7 times, resulting in a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 1007.0
Deduct 3626 from 3692 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 518

Step 7:
The number 518 fits into 666 1 times, leaving a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 10071.0
If we take 518 away from 666, we end up with 148.
Take the next digit (4) from the dividend and append it to 148, then repeat: 1484 / 518

Going ahead to step 8:
The number 518 fits into 1484 2 times, leaving a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 100712.0
If we take 1036 away from 1484, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 9:
518 goes into 4480 8 times with a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 100712.8
If we take 4144 away from 4480, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 10:
518 goes into 3360 6 times with a remainder of 252.
Use 6 as the next digit of our solution. 
Result so far: 100712.86
If we take 3108 away from 3360, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
If we divide 2520 by 518, we get 4 and a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 100712.864
If we subtract 2072 from 2520, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 12:
518 goes into 4480 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 100712.8648
If we take 4144 away from 4480, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 13:
518 can be fit into 3360 6 times, resulting in a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 100712.86486
Subtract 3108 from 3360 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 14:
518 goes into 2520 4 times with a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 100712.864864
Deduct 2072 from 2520 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 15:
When dividing 4480 by 518, we get 8 with a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 100712.8648648
If we take 4144 away from 4480, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 16:
When dividing 3360 by 518, we get 6 with a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 100712.86486486
If we take 3108 away from 3360, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final result is 100712.86486486 with a remainder of 2.52e-07.
