We look at the division of 33288330 by 518 
The aim is to understand the frequency of 518 in 33288330.

Moving on to step 1:
The number 518 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 518

Going ahead to step 2:
If we divide 33 by 518, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 518

Step 3:
518 goes into 332 0 times with a remainder of 332.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 332, we get 332.
Grab the next digit (8) from the dividend, add it to 332, then carry on: 3328 / 518

Let's proceed to step 4:
518 can be fit into 3328 6 times, resulting in a remainder of 220.
The next digit of our result is 6. 
Result so far: 6.0
If we take 3108 away from 3328, we end up with 220.
Grab the next digit (8) from the dividend, add it to 220, then carry on: 2208 / 518

Step 5:
If we divide 2208 by 518, we get 4 and a remainder of 136.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 2072 from 2208 to get 136.
Grab the next digit (3) from the dividend, add it to 136, then carry on: 1363 / 518

Moving on to step 6:
The number 518 fits into 1363 2 times, leaving a remainder of 327.
Put 2 as the next digit of the answer. 
Result so far: 642.0
Deduct 1036 from 1363 and we're left with 327.
Take the next digit (3) from the dividend and append it to 327, then repeat: 3273 / 518

Going ahead to step 7:
518 can be fit into 3273 6 times, resulting in a remainder of 165.
Write down 6 as next digit of the result. 
Result so far: 6426.0
The remainder is 165 after subtracting 3108 from 3273.
Include the next digit (0) from the dividend after 165, then repeat: 1650 / 518

On to step 8:
When dividing 1650 by 518, we get 3 with a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 64263.0
Deduct 1554 from 1650 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
When dividing 960 by 518, we get 1 with a remainder of 442.
Put 1 as the next digit of the answer. 
Result so far: 64263.1
If we subtract 518 from 960, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
518 goes into 4420 8 times with a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 64263.18
Deduct 4144 from 4420 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
The number 518 fits into 2760 5 times, leaving a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 64263.185
Deduct 2590 from 2760 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 12:
When dividing 1700 by 518, we get 3 with a remainder of 146.
The next digit of our result is 3. 
Result so far: 64263.1853
Subtract 1554 from 1700 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 13:
518 goes into 1460 2 times with a remainder of 424.
The next digit of our result is 2. 
Result so far: 64263.18532
Subtracting 1036 from 1460 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 14:
518 goes into 4240 8 times with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 64263.185328
Subtract 4144 from 4240 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
518 can be fit into 960 1 times, resulting in a remainder of 442.
Record the quotient 1 as the next digit in the result. 
Result so far: 64263.1853281
If we take 518 away from 960, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 16:
518 goes into 4420 8 times with a remainder of 276.
The next digit of our result is 8. 
Result so far: 64263.18532818
If we take 4144 away from 4420, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The quotient of the division is 64263.18532818, and the remainder is 2.76e-07.
