We look at the division of 15206125 by 517 
The aim is to understand the frequency of 517 in 15206125.

Going ahead to step 1:
When dividing 1 by 517, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 517

Advancing to step 2:
If we divide 15 by 517, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 517

Step 3:
517 can be fit into 152 0 times, resulting in a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 152 leaves us with 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 517

Advancing to step 4:
1520 divided by 517 is 2 with a remainder of 486.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1034 from 1520 leaves us with 486.
Take the next digit (6) from the dividend and append it to 486, then repeat: 4866 / 517

Advancing to step 5:
If we divide 4866 by 517, we get 9 and a remainder of 213.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 4653 from 4866 and we're left with 213.
Append the next digit (1) from the dividend to 213 and continue with: 2131 / 517

Step 6:
517 goes into 2131 4 times with a remainder of 63.
The next digit of our result is 4. 
Result so far: 294.0
Subtract 2068 from 2131 to get 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 517

Advancing to step 7:
517 can be fit into 632 1 times, resulting in a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 2941.0
If we take 517 away from 632, we end up with 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 517

Moving on to step 8:
517 can be fit into 1155 2 times, resulting in a remainder of 121.
The next digit of our result is 2. 
Result so far: 29412.0
Subtract 1034 from 1155 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
517 can be fit into 1210 2 times, resulting in a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 29412.2
Subtracting 1034 from 1210 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 10:
517 can be fit into 1760 3 times, resulting in a remainder of 209.
Use 3 as the next digit of our solution. 
Result so far: 29412.23
The remainder is 209 after subtracting 1551 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 11:
517 goes into 2090 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 29412.234
Subtracting 2068 from 2090 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 517 fits into 220 0 times, leaving a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 29412.234
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
2200 divided by 517 is 4 with a remainder of 132.
Write down 4 as next digit of the result. 
Result so far: 29412.23404
The remainder is 132 after subtracting 2068 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
1320 divided by 517 is 2 with a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 29412.234042
If we subtract 1034 from 1320, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 15:
The number 517 fits into 2860 5 times, leaving a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 29412.2340425
If we take 2585 away from 2860, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 16:
2750 divided by 517 is 5 with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 29412.23404255
Subtract 2585 from 2750 to 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.

In conclusion, the division gives 29412.23404255 with a balance of 1.65e-07.
