Let's divide 38443964 by 209
The aim is to understand the frequency of 209 in 38443964.

Let's proceed to step 1:
209 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 209

Going ahead to step 2:
209 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 209

Step 3:
209 can be fit into 384 1 times, resulting in a remainder of 175.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 175 after subtracting 209 from 384.
Fetch the next digit (4) from the dividend, attach it to 175 and continue: 1754 / 209

Going ahead to step 4:
When dividing 1754 by 209, we get 8 with a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 1672 away from 1754, we end up with 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 209

On to step 5:
823 divided by 209 is 3 with a remainder of 196.
The next digit of our result is 3. 
Result so far: 183.0
Subtracting 627 from 823 leaves us with 196.
Fetch the next digit (9) from the dividend, attach it to 196 and continue: 1969 / 209

Going ahead to step 6:
The number 209 fits into 1969 9 times, leaving a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 1839.0
If we subtract 1881 from 1969, we get 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 209

Moving on to step 7:
209 goes into 886 4 times with a remainder of 50.
The next digit of our result is 4. 
Result so far: 18394.0
If we take 836 away from 886, we end up with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 209

Step 8:
When dividing 504 by 209, we get 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 183942.0
Subtracting 418 from 504 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
860 divided by 209 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 183942.4
Subtract 836 from 860 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
209 goes into 240 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 183942.41
Deduct 209 from 240 and we're left 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.

Moving on to step 11:
310 divided by 209 is 1 with a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 183942.411
If we subtract 209 from 310, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

After the division, we end up with 183942.411 and a remainder of 0.0101.
