We look at the division of 12608966 by 799 
The aim is to understand the frequency of 799 in 12608966.

Advancing to step 1:
1 divided by 799 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 799

Advancing to step 2:
When dividing 12 by 799, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 799

Going ahead to step 3:
When dividing 126 by 799, we get 0 with a remainder of 126.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 799

Step 4:
If we divide 1260 by 799, we get 1 and a remainder of 461.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 461 after subtracting 799 from 1260.
Include the next digit (8) from the dividend after 461, then repeat: 4618 / 799

On to step 5:
If we divide 4618 by 799, we get 5 and a remainder of 623.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 3995 away from 4618, we end up with 623.
Fetch the next digit (9) from the dividend, attach it to 623 and continue: 6239 / 799

On to step 6:
If we divide 6239 by 799, we get 7 and a remainder of 646.
Write down 7 as next digit of the result. 
Result so far: 157.0
Subtract 5593 from 6239 to get 646.
Grab the next digit (6) from the dividend, add it to 646, then carry on: 6466 / 799

Step 7:
6466 divided by 799 is 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 1578.0
If we take 6392 away from 6466, we end up with 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 799

On to step 8:
When dividing 746 by 799, we get 0 with a remainder of 746.
The next digit of our result is 0. 
Result so far: 15780.0
Subtracting 0 from 746 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Step 9:
When dividing 7460 by 799, we get 9 with a remainder of 269.
Write down 9 as next digit of the result. 
Result so far: 15780.9
If we subtract 7191 from 7460, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 10:
If we divide 2690 by 799, we get 3 and a remainder of 293.
The number 3 becomes the next digit in our result. 
Result so far: 15780.93
The remainder is 293 after subtracting 2397 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 11:
799 can be fit into 2930 3 times, resulting in a remainder of 533.
Record the quotient 3 as the next digit in the result. 
Result so far: 15780.933
If we subtract 2397 from 2930, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

The final outcome is 15780.933, with a leftover of 0.0533.
