We're dividing 779950 by 79 
The aim is to understand the frequency of 79 in 779950.

Let's proceed to step 1:
7 divided by 79 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 79

Let's proceed to step 2:
The number 79 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 79

On to step 3:
79 goes into 779 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 68 after subtracting 711 from 779.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 79

Step 4:
689 divided by 79 is 8 with a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 632 from 689 to get 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 79

Let's proceed to step 5:
When dividing 575 by 79, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 987.0
Subtract 553 from 575 to get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 79

On to step 6:
The number 79 fits into 220 2 times, leaving a remainder of 62.
The next digit of our result is 2. 
Result so far: 9872.0
If we subtract 158 from 220, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
620 divided by 79 is 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 9872.7
Subtracting 553 from 620 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 8:
The number 79 fits into 670 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 9872.78
Deduct 632 from 670 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
If we divide 380 by 79, we get 4 and a remainder of 64.
The next digit of our result is 4. 
Result so far: 9872.784
If we subtract 316 from 380, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
The number 79 fits into 640 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 9872.7848
The remainder is 8 after subtracting 632 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 79, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 9872.78481
If we subtract 79 from 80, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
If we divide 10 by 79, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 9872.78481
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
79 can be fit into 100 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 9872.7848101
Subtracting 79 from 100 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
When dividing 210 by 79, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 9872.78481012
If we subtract 158 from 210, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 9872.78481012 and a remainder of 5.2e-08.
