93505520 ÷ 518 
The aim is to understand the frequency of 518 in 93505520.

On to step 1:
9 divided by 518 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 518

Moving on to step 2:
When dividing 93 by 518, we get 0 with a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Grab the next digit (5) from the dividend, add it to 93, then carry on: 935 / 518

On to step 3:
When dividing 935 by 518, we get 1 with a remainder of 417.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 518 from 935 leaves us with 417.
Fetch the next digit (0) from the dividend, attach it to 417 and continue: 4170 / 518

On to step 4:
4170 divided by 518 is 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 4144 away from 4170, we end up with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 518

Going ahead to step 5:
When dividing 265 by 518, we get 0 with a remainder of 265.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we take 0 away from 265, we end up with 265.
Include the next digit (5) from the dividend after 265, then repeat: 2655 / 518

Going ahead to step 6:
If we divide 2655 by 518, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 1805.0
If we subtract 2590 from 2655, we get 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 518

Moving on to step 7:
When dividing 652 by 518, we get 1 with a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 18051.0
Deduct 518 from 652 and we're left with 134.
Fetch the next digit (0) from the dividend, attach it to 134 and continue: 1340 / 518

Let's proceed to step 8:
518 can be fit into 1340 2 times, resulting in a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 180512.0
If we subtract 1036 from 1340, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
When dividing 3040 by 518, we get 5 with a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 180512.5
If we take 2590 away from 3040, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
The number 518 fits into 4500 8 times, leaving a remainder of 356.
The next digit of our result is 8. 
Result so far: 180512.58
Subtracting 4144 from 4500 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 11:
When dividing 3560 by 518, we get 6 with a remainder of 452.
The number 6 becomes the next digit in our result. 
Result so far: 180512.586
Deduct 3108 from 3560 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 12:
If we divide 4520 by 518, we get 8 and a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 180512.5868
Subtract 4144 from 4520 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 13:
If we divide 3760 by 518, we get 7 and a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 180512.58687
The remainder is 134 after subtracting 3626 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 14:
The number 518 fits into 1340 2 times, leaving a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 180512.586872
Deduct 1036 from 1340 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
When dividing 3040 by 518, we get 5 with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 180512.5868725
The remainder is 450 after subtracting 2590 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
4500 divided by 518 is 8 with a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 180512.58687258
If we take 4144 away from 4500, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final result is 180512.58687258 with a remainder of 3.56e-07.
