We look at the division of 27351715 by 518 
The aim is to understand the frequency of 518 in 27351715.

Moving on to step 1:
518 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 518

Going ahead to step 2:
27 divided by 518 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 518

Moving on to step 3:
273 divided by 518 is 0 with a remainder of 273.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 273 and we're left with 273.
Bring next digit (5) of the dividend behind the 273 and repeat the process: 2735 / 518

Advancing to step 4:
518 can be fit into 2735 5 times, resulting in a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 2590 from 2735, we get 145.
Grab the next digit (1) from the dividend, add it to 145, then carry on: 1451 / 518

Advancing to step 5:
518 goes into 1451 2 times with a remainder of 415.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtract 1036 from 1451 to get 415.
Bring next digit (7) of the dividend behind the 415 and repeat the process: 4157 / 518

Let's proceed to step 6:
518 can be fit into 4157 8 times, resulting in a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 528.0
The remainder is 13 after subtracting 4144 from 4157.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 518

Going ahead to step 7:
518 goes into 131 0 times with a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 5280.0
Subtract 0 from 131 to get 131.
Grab the next digit (5) from the dividend, add it to 131, then carry on: 1315 / 518

Step 8:
518 goes into 1315 2 times with a remainder of 279.
Record the quotient 2 as the next digit in the result. 
Result so far: 52802.0
Subtract 1036 from 1315 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 9:
When dividing 2790 by 518, we get 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 52802.5
Deduct 2590 from 2790 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.

Going ahead to step 10:
When dividing 2000 by 518, we get 3 with a remainder of 446.
Record the quotient 3 as the next digit in the result. 
Result so far: 52802.53
Subtracting 1554 from 2000 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 11:
When dividing 4460 by 518, we get 8 with a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 52802.538
Subtract 4144 from 4460 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 12:
When dividing 3160 by 518, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 52802.5386
If we take 3108 away from 3160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
518 can be fit into 520 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 52802.53861
Subtract 518 from 520 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
When dividing 20 by 518, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 52802.53861
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 15:
518 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 52802.53861
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 52802.53861, with a leftover of 2e-06.
