We're dividing 4406731 by 209 
The aim is to understand the frequency of 209 in 4406731.

Step 1:
The number 209 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 209

Let's proceed to step 2:
If we divide 44 by 209, we get 0 and a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 209

Let's proceed to step 3:
440 divided by 209 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 418 from 440 to get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 209

Advancing to step 4:
The number 209 fits into 226 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 209 from 226 leaves us with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 209

Let's proceed to step 5:
The number 209 fits into 177 0 times, leaving a remainder of 177.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
The remainder is 177 after subtracting 0 from 177.
Include the next digit (3) from the dividend after 177, then repeat: 1773 / 209

Advancing to step 6:
When dividing 1773 by 209, we get 8 with a remainder of 101.
Write down 8 as next digit of the result. 
Result so far: 2108.0
Subtract 1672 from 1773 to get 101.
Take the next digit (1) from the dividend and append it to 101, then repeat: 1011 / 209

Step 7:
If we divide 1011 by 209, we get 4 and a remainder of 175.
Put 4 as the next digit of the answer. 
Result so far: 21084.0
If we subtract 836 from 1011, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 8:
The number 209 fits into 1750 8 times, leaving a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 21084.8
Subtract 1672 from 1750 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
The number 209 fits into 780 3 times, leaving a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 21084.83
If we take 627 away from 780, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 10:
1530 divided by 209 is 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 21084.837
Subtract 1463 from 1530 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 11:
The number 209 fits into 670 3 times, leaving a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 21084.8373
The remainder is 43 after subtracting 627 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
209 can be fit into 430 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 21084.83732
Subtracting 418 from 430 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
The number 209 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 21084.83732
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
209 goes into 1200 5 times with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 21084.8373205
Deduct 1045 from 1200 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 15:
209 goes into 1550 7 times with a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 21084.83732057
If we subtract 1463 from 1550, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final outcome is 21084.83732057, with a leftover of 8.7e-08.
