We look at the division of 17765902 by 206 
The aim is to understand the frequency of 206 in 17765902.

Going ahead to step 1:
1 divided by 206 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 206

Step 2:
If we divide 17 by 206, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 206

Advancing to step 3:
206 goes into 177 0 times with a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 177 leaves us with 177.
Append the next digit (6) from the dividend to 177 and continue with: 1776 / 206

Step 4:
The number 206 fits into 1776 8 times, leaving a remainder of 128.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 1648 from 1776 to get 128.
Include the next digit (5) from the dividend after 128, then repeat: 1285 / 206

Advancing to step 5:
1285 divided by 206 is 6 with a remainder of 49.
The next digit of our result is 6. 
Result so far: 86.0
If we take 1236 away from 1285, we end up with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 206

Step 6:
When dividing 499 by 206, we get 2 with a remainder of 87.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
Deduct 412 from 499 and we're left with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 206

Let's proceed to step 7:
The number 206 fits into 870 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 8624.0
If we subtract 824 from 870, we get 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 206

Let's proceed to step 8:
462 divided by 206 is 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 86242.0
Subtract 412 from 462 to get 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 9:
206 can be fit into 500 2 times, resulting in a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 86242.2
Subtracting 412 from 500 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
206 can be fit into 880 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 86242.24
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.

On to step 11:
If we divide 560 by 206, we get 2 and a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 86242.242
If we take 412 away from 560, we end up 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.

On to step 12:
206 goes into 1480 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 86242.2427
Subtract 1442 from 1480 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 206, we get 1 with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 86242.24271
The remainder is 174 after subtracting 206 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 14:
1740 divided by 206 is 8 with a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 86242.242718
If we subtract 1648 from 1740, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 15:
When dividing 920 by 206, we get 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 86242.2427184
The remainder is 96 after subtracting 824 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
206 goes into 960 4 times with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 86242.24271844
If we subtract 824 from 960, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 86242.24271844 and a remainder of 1.36e-07.
