We look at the division of 54339691 by 579 
The aim is to understand the frequency of 579 in 54339691.

Going ahead to step 1:
If we divide 5 by 579, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 579

Going ahead to step 2:
579 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 579

Advancing to step 3:
The number 579 fits into 543 0 times, leaving a remainder of 543.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 543 after subtracting 0 from 543.
Take the next digit (3) from the dividend and append it to 543, then repeat: 5433 / 579

Going ahead to step 4:
579 can be fit into 5433 9 times, resulting in a remainder of 222.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 222 after subtracting 5211 from 5433.
Grab the next digit (9) from the dividend, add it to 222, then carry on: 2229 / 579

On to step 5:
If we divide 2229 by 579, we get 3 and a remainder of 492.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 1737 away from 2229, we end up with 492.
Include the next digit (6) from the dividend after 492, then repeat: 4926 / 579

Moving on to step 6:
When dividing 4926 by 579, we get 8 with a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 938.0
Subtracting 4632 from 4926 leaves us with 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 579

Step 7:
579 can be fit into 2949 5 times, resulting in a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 9385.0
If we take 2895 away from 2949, we end up with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 579

Going ahead to step 8:
When dividing 541 by 579, we get 0 with a remainder of 541.
Put 0 as the next digit of the answer. 
Result so far: 93850.0
Subtracting 0 from 541 leaves us with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Going ahead to step 9:
The number 579 fits into 5410 9 times, leaving a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 93850.9
Subtract 5211 from 5410 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 10:
579 goes into 1990 3 times with a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 93850.93
The remainder is 253 after subtracting 1737 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 11:
579 goes into 2530 4 times with a remainder of 214.
The next digit of our result is 4. 
Result so far: 93850.934
The remainder is 214 after subtracting 2316 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 12:
2140 divided by 579 is 3 with a remainder of 403.
The number 3 becomes the next digit in our result. 
Result so far: 93850.9343
Deduct 1737 from 2140 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 13:
579 goes into 4030 6 times with a remainder of 556.
Put 6 as the next digit of the answer. 
Result so far: 93850.93436
If we subtract 3474 from 4030, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 14:
579 can be fit into 5560 9 times, resulting in a remainder of 349.
The number 9 becomes the next digit in our result. 
Result so far: 93850.934369
Deduct 5211 from 5560 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 15:
The number 579 fits into 3490 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 93850.9343696
Subtracting 3474 from 3490 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
579 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 93850.9343696
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 93850.9343696 with a remainder of 1.6e-07.
