We look at the division of 768168 by 79 
The aim is to understand the frequency of 79 in 768168.

Step 1:
79 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 79

Moving on to step 2:
79 can be fit into 76 0 times, resulting in a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 79

Going ahead to step 3:
768 divided by 79 is 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 711 from 768, we get 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 79

Advancing to step 4:
The number 79 fits into 571 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 553 from 571 and we're left with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 79

Advancing to step 5:
186 divided by 79 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 972.0
Subtracting 158 from 186 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 79

On to step 6:
The number 79 fits into 288 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 9723.0
The remainder is 51 after subtracting 237 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
When dividing 510 by 79, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 9723.6
Subtract 474 from 510 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 79, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 9723.64
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.

Advancing to step 9:
If we divide 440 by 79, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 9723.645
Subtracting 395 from 440 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
The number 79 fits into 450 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 9723.6455
Subtracting 395 from 450 leaves us with 55.
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 9723.6455, with a leftover of 0.00055.
