We look at the division of 266249 by 79 
The aim is to understand the frequency of 79 in 266249.

Step 1:
If we divide 2 by 79, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 79

Let's proceed to step 2:
26 divided by 79 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 79

On to step 3:
When dividing 266 by 79, we get 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 237 away from 266, we end up with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 79

Advancing to step 4:
79 can be fit into 292 3 times, resulting in a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 237 from 292 and we're left with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 79

Advancing to step 5:
If we divide 554 by 79, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 337.0
The remainder is 1 after subtracting 553 from 554.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 79

Going ahead to step 6:
If we divide 19 by 79, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 3370.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
If we divide 190 by 79, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 3370.2
If we take 158 away from 190, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
320 divided by 79 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 3370.24
Deduct 316 from 320 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 79 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 3370.24
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 79, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3370.2405
Subtract 395 from 400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 79 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 3370.2405
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
500 divided by 79 is 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 3370.240506
Deduct 474 from 500 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
If we divide 260 by 79, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3370.2405063
Subtracting 237 from 260 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
When dividing 230 by 79, we get 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 3370.24050632
Subtracting 158 from 230 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 3370.24050632 with a balance of 7.2e-08.
