We look at the division of 17343121 by 579 
The aim is to understand the frequency of 579 in 17343121.

Going ahead to step 1:
1 divided by 579 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 579

On to step 2:
If we divide 17 by 579, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 579

On to step 3:
579 can be fit into 173 0 times, resulting in a remainder of 173.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 173 after subtracting 0 from 173.
Fetch the next digit (4) from the dividend, attach it to 173 and continue: 1734 / 579

On to step 4:
The number 579 fits into 1734 2 times, leaving a remainder of 576.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1158 from 1734, we get 576.
Include the next digit (3) from the dividend after 576, then repeat: 5763 / 579

Step 5:
When dividing 5763 by 579, we get 9 with a remainder of 552.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 5211 from 5763 and we're left with 552.
Include the next digit (1) from the dividend after 552, then repeat: 5521 / 579

Let's proceed to step 6:
When dividing 5521 by 579, we get 9 with a remainder of 310.
Use 9 as the next digit of our solution. 
Result so far: 299.0
Subtracting 5211 from 5521 leaves us with 310.
Take the next digit (2) from the dividend and append it to 310, then repeat: 3102 / 579

Step 7:
The number 579 fits into 3102 5 times, leaving a remainder of 207.
The next digit of our result is 5. 
Result so far: 2995.0
Deduct 2895 from 3102 and we're left with 207.
Include the next digit (1) from the dividend after 207, then repeat: 2071 / 579

Let's proceed to step 8:
When dividing 2071 by 579, we get 3 with a remainder of 334.
The number 3 becomes the next digit in our result. 
Result so far: 29953.0
If we take 1737 away from 2071, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 9:
579 can be fit into 3340 5 times, resulting in a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 29953.5
The remainder is 445 after subtracting 2895 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 10:
579 can be fit into 4450 7 times, resulting in a remainder of 397.
Use 7 as the next digit of our solution. 
Result so far: 29953.57
Subtract 4053 from 4450 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 11:
If we divide 3970 by 579, we get 6 and a remainder of 496.
Record the quotient 6 as the next digit in the result. 
Result so far: 29953.576
If we subtract 3474 from 3970, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 12:
4960 divided by 579 is 8 with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 29953.5768
The remainder is 328 after subtracting 4632 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 13:
When dividing 3280 by 579, we get 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 29953.57685
If we take 2895 away from 3280, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 14:
The number 579 fits into 3850 6 times, leaving a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 29953.576856
The remainder is 376 after subtracting 3474 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 15:
If we divide 3760 by 579, we get 6 and a remainder of 286.
The number 6 becomes the next digit in our result. 
Result so far: 29953.5768566
Subtract 3474 from 3760 to 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.

The final outcome is 29953.5768566, with a leftover of 2.86e-06.
