We're dividing 665944 by 79 
The aim is to understand the frequency of 79 in 665944.

Moving on to step 1:
6 divided by 79 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 79

Let's proceed to step 2:
66 divided by 79 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 79

Advancing to step 3:
665 divided by 79 is 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 632 from 665 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 79

Advancing to step 4:
339 divided by 79 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 316 from 339 and we're left with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 79

Going ahead to step 5:
If we divide 234 by 79, we get 2 and a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 842.0
Subtract 158 from 234 to get 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 79

On to step 6:
When dividing 764 by 79, we get 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 8429.0
Deduct 711 from 764 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
79 can be fit into 530 6 times, resulting in a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 8429.6
Subtracting 474 from 530 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
79 goes into 560 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 8429.67
Subtract 553 from 560 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 79, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 8429.67
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
When dividing 700 by 79, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 8429.6708
Deduct 632 from 700 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
680 divided by 79 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 8429.67088
Subtract 632 from 680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 8429.67088 with a remainder of 4.8e-05.
