We look at the division of 33720712 by 209 
The aim is to understand the frequency of 209 in 33720712.

Advancing to step 1:
3 divided by 209 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 209

Let's proceed to step 2:
209 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 209

Moving on to step 3:
337 divided by 209 is 1 with a remainder of 128.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 209 from 337, we get 128.
Grab the next digit (2) from the dividend, add it to 128, then carry on: 1282 / 209

Step 4:
209 goes into 1282 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 1254 from 1282 and we're left with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 209

Advancing to step 5:
209 can be fit into 280 1 times, resulting in a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Deduct 209 from 280 and we're left with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 209

Advancing to step 6:
209 can be fit into 717 3 times, resulting in a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 1613.0
Subtracting 627 from 717 leaves us with 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 209

Going ahead to step 7:
If we divide 901 by 209, we get 4 and a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 16134.0
If we take 836 away from 901, we end up with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 209

Let's proceed to step 8:
If we divide 652 by 209, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 161343.0
If we subtract 627 from 652, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
209 goes into 250 1 times with a remainder of 41.
The next digit of our result is 1. 
Result so far: 161343.1
If we take 209 away from 250, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
209 can be fit into 410 1 times, resulting in a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 161343.11
The remainder is 201 after subtracting 209 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final outcome is 161343.11, with a leftover of 0.201.
