We're dividing 129365 by 79 
The aim is to understand the frequency of 79 in 129365.

Step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 79

Step 2:
79 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 79

Step 3:
The number 79 fits into 129 1 times, leaving a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 79 away from 129, we end up with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 79

Let's proceed to step 4:
If we divide 503 by 79, we get 6 and a remainder of 29.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 474 from 503 and we're left with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 79

Advancing to step 5:
79 goes into 296 3 times with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 163.0
The remainder is 59 after subtracting 237 from 296.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 79

Going ahead to step 6:
If we divide 595 by 79, we get 7 and a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 1637.0
If we subtract 553 from 595, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 79 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1637.5
If we subtract 395 from 420, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
The number 79 fits into 250 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1637.53
If we subtract 237 from 250, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 79, we get 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1637.531
Subtract 79 from 130 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
When dividing 510 by 79, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1637.5316
Subtracting 474 from 510 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 79, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 1637.53164
Subtract 316 from 360 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
When dividing 440 by 79, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1637.531645
If we subtract 395 from 440, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
450 divided by 79 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 1637.5316455
The remainder is 55 after subtracting 395 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 1637.5316455, with a leftover of 5.5e-07.
