We look at the division of 61172717 by 579 
The aim is to understand the frequency of 579 in 61172717.

Step 1:
579 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 579

Going ahead to step 2:
579 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 579

Going ahead to step 3:
611 divided by 579 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 32 after subtracting 579 from 611.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 579

Moving on to step 4:
579 goes into 327 0 times with a remainder of 327.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 327, we get 327.
Append the next digit (2) from the dividend to 327 and continue with: 3272 / 579

Going ahead to step 5:
3272 divided by 579 is 5 with a remainder of 377.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
The remainder is 377 after subtracting 2895 from 3272.
Append the next digit (7) from the dividend to 377 and continue with: 3777 / 579

Let's proceed to step 6:
579 can be fit into 3777 6 times, resulting in a remainder of 303.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
If we subtract 3474 from 3777, we get 303.
Append the next digit (1) from the dividend to 303 and continue with: 3031 / 579

Step 7:
If we divide 3031 by 579, we get 5 and a remainder of 136.
Use 5 as the next digit of our solution. 
Result so far: 10565.0
The remainder is 136 after subtracting 2895 from 3031.
Grab the next digit (7) from the dividend, add it to 136, then carry on: 1367 / 579

Step 8:
579 goes into 1367 2 times with a remainder of 209.
Use 2 as the next digit of our solution. 
Result so far: 105652.0
Subtracting 1158 from 1367 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
579 goes into 2090 3 times with a remainder of 353.
The next digit of our result is 3. 
Result so far: 105652.3
If we take 1737 away from 2090, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 10:
579 goes into 3530 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 105652.36
Subtracting 3474 from 3530 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
579 can be fit into 560 0 times, resulting in a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 105652.36
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 12:
579 can be fit into 5600 9 times, resulting in a remainder of 389.
Use 9 as the next digit of our solution. 
Result so far: 105652.3609
The remainder is 389 after subtracting 5211 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 13:
The number 579 fits into 3890 6 times, leaving a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 105652.36096
If we take 3474 away from 3890, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 14:
579 goes into 4160 7 times with a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 105652.360967
The remainder is 107 after subtracting 4053 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 15:
The number 579 fits into 1070 1 times, leaving a remainder of 491.
Put 1 as the next digit of the answer. 
Result so far: 105652.3609671
Subtract 579 from 1070 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 16:
4910 divided by 579 is 8 with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 105652.36096718
If we take 4632 away from 4910, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 105652.36096718, with a leftover of 2.78e-07.
