We look at the division of 522644 by 79 
The aim is to understand the frequency of 79 in 522644.

Step 1:
5 divided by 79 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 79

Going ahead to step 2:
When dividing 52 by 79, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 79

Moving on to step 3:
522 divided by 79 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6.0
If we take 474 away from 522, we end up with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 79

Advancing to step 4:
486 divided by 79 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 474 from 486 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 79

On to step 5:
If we divide 124 by 79, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 661.0
If we take 79 away from 124, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 79

Step 6:
When dividing 454 by 79, we get 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 6615.0
The remainder is 59 after subtracting 395 from 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
When dividing 590 by 79, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 6615.7
Subtract 553 from 590 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
370 divided by 79 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 6615.74
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
540 divided by 79 is 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 6615.746
The remainder is 66 after subtracting 474 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
When dividing 660 by 79, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 6615.7468
Deduct 632 from 660 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
79 can be fit into 280 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 6615.74683
Subtracting 237 from 280 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
The number 79 fits into 430 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 6615.746835
The remainder is 35 after subtracting 395 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
350 divided by 79 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 6615.7468354
Subtracting 316 from 350 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
79 can be fit into 340 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 6615.74683544
The remainder is 24 after subtracting 316 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 6615.74683544, with a leftover of 2.4e-08.
