We look at the division of 39952284 by 209 
The aim is to understand the frequency of 209 in 39952284.

On to step 1:
When dividing 3 by 209, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 209

Advancing to step 2:
If we divide 39 by 209, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 209

Let's proceed to step 3:
399 divided by 209 is 1 with a remainder of 190.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 209 from 399, we get 190.
Fetch the next digit (5) from the dividend, attach it to 190 and continue: 1905 / 209

Moving on to step 4:
209 goes into 1905 9 times with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 24 after subtracting 1881 from 1905.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 209

Advancing to step 5:
If we divide 242 by 209, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we subtract 209 from 242, we get 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 209

Going ahead to step 6:
When dividing 332 by 209, we get 1 with a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 1911.0
Subtract 209 from 332 to get 123.
Bring next digit (8) of the dividend behind the 123 and repeat the process: 1238 / 209

Going ahead to step 7:
When dividing 1238 by 209, we get 5 with a remainder of 193.
Put 5 as the next digit of the answer. 
Result so far: 19115.0
Subtracting 1045 from 1238 leaves us with 193.
Bring next digit (4) of the dividend behind the 193 and repeat the process: 1934 / 209

Step 8:
When dividing 1934 by 209, we get 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 191159.0
The remainder is 53 after subtracting 1881 from 1934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
209 goes into 530 2 times with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 191159.2
If we subtract 418 from 530, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 10:
1120 divided by 209 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 191159.25
The remainder is 75 after subtracting 1045 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
If we divide 750 by 209, we get 3 and a remainder of 123.
The next digit of our result is 3. 
Result so far: 191159.253
If we take 627 away from 750, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 12:
When dividing 1230 by 209, we get 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 191159.2535
The remainder is 185 after subtracting 1045 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 13:
209 can be fit into 1850 8 times, resulting in a remainder of 178.
Record the quotient 8 as the next digit in the result. 
Result so far: 191159.25358
Deduct 1672 from 1850 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 14:
The number 209 fits into 1780 8 times, leaving a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 191159.253588
Deduct 1672 from 1780 and we're left 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.

After the division, we end up with 191159.253588 and a remainder of 1.08e-05.
