We look at the division of 79499739 by 79 
The aim is to understand the frequency of 79 in 79499739.

Going ahead to step 1:
The number 79 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 79

Going ahead to step 2:
79 goes into 79 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 79 from 79 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 79

Going ahead to step 3:
The number 79 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 79

On to step 4:
79 can be fit into 49 0 times, resulting in a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 49, we end up with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 79

Moving on to step 5:
499 divided by 79 is 6 with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
If we subtract 474 from 499, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 79

Let's proceed to step 6:
79 can be fit into 257 3 times, resulting in a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 10063.0
If we take 237 away from 257, we end up with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 79

Advancing to step 7:
79 goes into 203 2 times with a remainder of 45.
The next digit of our result is 2. 
Result so far: 100632.0
Subtract 158 from 203 to get 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 79

Step 8:
If we divide 459 by 79, we get 5 and a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 1006325.0
If we subtract 395 from 459, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
640 divided by 79 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1006325.8
The remainder is 8 after subtracting 632 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
If we divide 80 by 79, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1006325.81
Subtracting 79 from 80 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
79 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1006325.81
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
79 goes into 100 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1006325.8101
Subtract 79 from 100 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
The number 79 fits into 210 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 1006325.81012
Deduct 158 from 210 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
The number 79 fits into 520 6 times, leaving a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 1006325.810126
Subtracting 474 from 520 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 15:
460 divided by 79 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1006325.8101265
The remainder is 65 after subtracting 395 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 16:
79 can be fit into 650 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1006325.81012658
If we take 632 away from 650, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 1006325.81012658 with a remainder of 1.8e-08.
