We look at the division of 29992369 by 517 
The aim is to understand the frequency of 517 in 29992369.

On to step 1:
The number 517 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 517

On to step 2:
The number 517 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 517

Going ahead to step 3:
When dividing 299 by 517, we get 0 with a remainder of 299.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 299 to get 299.
Grab the next digit (9) from the dividend, add it to 299, then carry on: 2999 / 517

Going ahead to step 4:
The number 517 fits into 2999 5 times, leaving a remainder of 414.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 2585 from 2999 leaves us with 414.
Append the next digit (2) from the dividend to 414 and continue with: 4142 / 517

On to step 5:
4142 divided by 517 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we subtract 4136 from 4142, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 517

Step 6:
When dividing 63 by 517, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 580.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 517

Step 7:
517 goes into 636 1 times with a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 5801.0
Deduct 517 from 636 and we're left with 119.
Grab the next digit (9) from the dividend, add it to 119, then carry on: 1199 / 517

On to step 8:
If we divide 1199 by 517, we get 2 and a remainder of 165.
Write down 2 as next digit of the result. 
Result so far: 58012.0
If we subtract 1034 from 1199, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 9:
The number 517 fits into 1650 3 times, leaving a remainder of 99.
Write down 3 as next digit of the result. 
Result so far: 58012.3
If we take 1551 away from 1650, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 10:
517 goes into 990 1 times with a remainder of 473.
Use 1 as the next digit of our solution. 
Result so far: 58012.31
Subtracting 517 from 990 leaves us 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.

On to step 11:
517 can be fit into 4730 9 times, resulting in a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 58012.319
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.

Moving on to step 12:
If we divide 770 by 517, we get 1 and a remainder of 253.
Record the quotient 1 as the next digit in the result. 
Result so far: 58012.3191
If we subtract 517 from 770, we 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 13:
When dividing 2530 by 517, we get 4 with a remainder of 462.
Write down 4 as next digit of the result. 
Result so far: 58012.31914
The remainder is 462 after subtracting 2068 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 14:
517 goes into 4620 8 times with a remainder of 484.
Use 8 as the next digit of our solution. 
Result so far: 58012.319148
Deduct 4136 from 4620 and we're left 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.

Advancing to step 15:
If we divide 4840 by 517, we get 9 and a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 58012.3191489
If we subtract 4653 from 4840, we get 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 16:
517 goes into 1870 3 times with a remainder of 319.
Use 3 as the next digit of our solution. 
Result so far: 58012.31914893
Subtract 1551 from 1870 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

The quotient of the division is 58012.31914893, and the remainder is 3.19e-07.
