Let's divide 16887904 by 517
The aim is to understand the frequency of 517 in 16887904.

On to step 1:
517 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 517

Going ahead to step 2:
When dividing 16 by 517, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 517

Advancing to step 3:
168 divided by 517 is 0 with a remainder of 168.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Take the next digit (8) from the dividend and append it to 168, then repeat: 1688 / 517

Moving on to step 4:
517 can be fit into 1688 3 times, resulting in a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1551 from 1688 and we're left with 137.
Bring next digit (7) of the dividend behind the 137 and repeat the process: 1377 / 517

Advancing to step 5:
If we divide 1377 by 517, we get 2 and a remainder of 343.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 1034 from 1377 to get 343.
Take the next digit (9) from the dividend and append it to 343, then repeat: 3439 / 517

Going ahead to step 6:
The number 517 fits into 3439 6 times, leaving a remainder of 337.
Write down 6 as next digit of the result. 
Result so far: 326.0
The remainder is 337 after subtracting 3102 from 3439.
Grab the next digit (0) from the dividend, add it to 337, then carry on: 3370 / 517

Let's proceed to step 7:
517 can be fit into 3370 6 times, resulting in a remainder of 268.
The number 6 becomes the next digit in our result. 
Result so far: 3266.0
Subtracting 3102 from 3370 leaves us with 268.
Take the next digit (4) from the dividend and append it to 268, then repeat: 2684 / 517

Going ahead to step 8:
517 can be fit into 2684 5 times, resulting in a remainder of 99.
The next digit of our result is 5. 
Result so far: 32665.0
The remainder is 99 after subtracting 2585 from 2684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
When dividing 990 by 517, we get 1 with a remainder of 473.
Use 1 as the next digit of our solution. 
Result so far: 32665.1
Deduct 517 from 990 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 10:
The number 517 fits into 4730 9 times, leaving a remainder of 77.
The next digit of our result is 9. 
Result so far: 32665.19
Deduct 4653 from 4730 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 11:
The number 517 fits into 770 1 times, leaving a remainder of 253.
Write down 1 as next digit of the result. 
Result so far: 32665.191
Subtract 517 from 770 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 12:
517 goes into 2530 4 times with a remainder of 462.
Write down 4 as next digit of the result. 
Result so far: 32665.1914
Subtract 2068 from 2530 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 13:
517 goes into 4620 8 times with a remainder of 484.
The number 8 becomes the next digit in our result. 
Result so far: 32665.19148
Subtracting 4136 from 4620 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 14:
When dividing 4840 by 517, we get 9 with a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 32665.191489
Subtracting 4653 from 4840 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 15:
When dividing 1870 by 517, we get 3 with a remainder of 319.
Write down 3 as next digit of the result. 
Result so far: 32665.1914893
Subtracting 1551 from 1870 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 16:
3190 divided by 517 is 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 32665.19148936
Subtracting 3102 from 3190 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 32665.19148936, and the remainder is 8.8e-08.
