We're dividing 660876 by 79 
The aim is to understand the frequency of 79 in 660876.

Moving on 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
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 79

Advancing to step 2:
66 divided by 79 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 79

Moving on to step 3:
The number 79 fits into 660 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 632 away from 660, we end up with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 79

On to step 4:
When dividing 288 by 79, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we subtract 237 from 288, we get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 79

On to step 5:
The number 79 fits into 517 6 times, leaving a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 836.0
If we subtract 474 from 517, we get 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 79

Let's proceed to step 6:
79 goes into 436 5 times with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 8365.0
Subtracting 395 from 436 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
The number 79 fits into 410 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8365.5
Subtracting 395 from 410 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 79, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 8365.51
The remainder is 71 after subtracting 79 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
79 goes into 710 8 times with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 8365.518
If we take 632 away from 710, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
79 goes into 780 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 8365.5189
Subtracting 711 from 780 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 11:
690 divided by 79 is 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 8365.51898
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
The number 79 fits into 580 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 8365.518987
Subtract 553 from 580 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
When dividing 270 by 79, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 8365.5189873
Subtracting 237 from 270 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 14:
79 can be fit into 330 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 8365.51898734
Deduct 316 from 330 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 8365.51898734 with a remainder of 1.4e-08.
