768172 divided by 79 
The aim is to understand the frequency of 79 in 768172.

Going ahead to step 1:
When dividing 7 by 79, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 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
Subtracting 0 from 76 leaves us with 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 79

Let's proceed to step 3:
The number 79 fits into 768 9 times, leaving a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 711 from 768 leaves us with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 79

Let's proceed to step 4:
79 can be fit into 571 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 553 from 571 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 79

Advancing to step 5:
The number 79 fits into 187 2 times, leaving a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
If we take 158 away from 187, we end up with 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 79

On to step 6:
If we divide 292 by 79, we get 3 and a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 9723.0
Subtract 237 from 292 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
79 goes into 550 6 times with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 9723.6
Subtracting 474 from 550 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
79 can be fit into 760 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 9723.69
If we subtract 711 from 760, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
79 goes into 490 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 9723.696
Subtracting 474 from 490 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 79, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 9723.6962
The remainder is 2 after subtracting 158 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
79 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9723.6962
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 79 is 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 9723.696202
The remainder is 42 after subtracting 158 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
The number 79 fits into 420 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 9723.6962025
Subtracting 395 from 420 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
250 divided by 79 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 9723.69620253
Subtracting 237 from 250 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 9723.69620253, with a leftover of 1.3e-08.
