26456405 divided by 206 
The aim is to understand the frequency of 206 in 26456405.

Advancing to step 1:
206 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 206

On to step 2:
206 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 206

Moving on to step 3:
When dividing 264 by 206, we get 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 58 after subtracting 206 from 264.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 206

On to step 4:
The number 206 fits into 585 2 times, leaving a remainder of 173.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 173 after subtracting 412 from 585.
Include the next digit (6) from the dividend after 173, then repeat: 1736 / 206

Going ahead to step 5:
When dividing 1736 by 206, we get 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtracting 1648 from 1736 leaves us with 88.
Grab the next digit (4) from the dividend, add it to 88, then carry on: 884 / 206

Moving on to step 6:
884 divided by 206 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1284.0
Deduct 824 from 884 and we're left with 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 206

Step 7:
206 can be fit into 600 2 times, resulting in a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 12842.0
The remainder is 188 after subtracting 412 from 600.
Take the next digit (5) from the dividend and append it to 188, then repeat: 1885 / 206

Let's proceed to step 8:
When dividing 1885 by 206, we get 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 128429.0
If we take 1854 away from 1885, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
When dividing 310 by 206, we get 1 with a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 128429.1
Subtract 206 from 310 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
The number 206 fits into 1040 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 128429.15
Deduct 1030 from 1040 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.

Going ahead to step 11:
100 divided by 206 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 128429.15
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
1000 divided by 206 is 4 with a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 128429.1504
The remainder is 176 after subtracting 824 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
206 goes into 1760 8 times with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 128429.15048
Subtracting 1648 from 1760 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 14:
When dividing 1120 by 206, we get 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 128429.150485
Subtracting 1030 from 1120 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
900 divided by 206 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 128429.1504854
Subtracting 824 from 900 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
760 divided by 206 is 3 with a remainder of 142.
Put 3 as the next digit of the answer. 
Result so far: 128429.15048543
Deduct 618 from 760 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 128429.15048543 with a remainder of 1.42e-07.
