We're dividing 6129865 by 79 
The aim is to understand the frequency of 79 in 6129865.

Let's proceed to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 79

On to step 2:
79 can be fit into 61 0 times, resulting in a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 79

Going ahead to step 3:
If we divide 612 by 79, we get 7 and a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 553 from 612 to get 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 79

Advancing to step 4:
79 can be fit into 599 7 times, resulting in a remainder of 46.
The next digit of our result is 7. 
Result so far: 77.0
Subtract 553 from 599 to get 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 79

Let's proceed to step 5:
If we divide 468 by 79, we get 5 and a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 775.0
Subtracting 395 from 468 leaves us with 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 79

Going ahead to step 6:
If we divide 736 by 79, we get 9 and a remainder of 25.
The next digit of our result is 9. 
Result so far: 7759.0
If we subtract 711 from 736, we get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 79

Let's proceed to step 7:
The number 79 fits into 255 3 times, leaving a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 77593.0
Subtract 237 from 255 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
If we divide 180 by 79, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 77593.2
The remainder is 22 after subtracting 158 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
79 goes into 220 2 times with a remainder of 62.
The next digit of our result is 2. 
Result so far: 77593.22
Deduct 158 from 220 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 77593.22 with a balance of 0.062.
