We look at the division of 23097870 by 206 
The aim is to understand the frequency of 206 in 23097870.

Step 1:
206 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 206

On to step 2:
206 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 206

Going ahead to step 3:
206 can be fit into 230 1 times, resulting in a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 206 from 230, we get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 206

Advancing to step 4:
249 divided by 206 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 206 from 249 and we're left with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 206

Moving on to step 5:
437 divided by 206 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 412 from 437 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 206

Advancing to step 6:
258 divided by 206 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 1121.0
Subtracting 206 from 258 leaves us with 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 206

On to step 7:
When dividing 527 by 206, we get 2 with a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 11212.0
If we subtract 412 from 527, we get 115.
Grab the next digit (0) from the dividend, add it to 115, then carry on: 1150 / 206

Moving on to step 8:
If we divide 1150 by 206, we get 5 and a remainder of 120.
The next digit of our result is 5. 
Result so far: 112125.0
Subtract 1030 from 1150 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 9:
206 can be fit into 1200 5 times, resulting in a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 112125.5
Subtract 1030 from 1200 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
206 can be fit into 1700 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 112125.58
Deduct 1648 from 1700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
The number 206 fits into 520 2 times, leaving a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 112125.582
If we take 412 away from 520, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
206 goes into 1080 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 112125.5825
The remainder is 50 after subtracting 1030 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 206, we get 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 112125.58252
Subtract 412 from 500 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
If we divide 880 by 206, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 112125.582524
If we subtract 824 from 880, we get 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 15:
560 divided by 206 is 2 with a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 112125.5825242
Subtracting 412 from 560 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 16:
1480 divided by 206 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 112125.58252427
Deduct 1442 from 1480 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.

The final result is 112125.58252427 with a remainder of 3.8e-08.
