18074245 ÷ 209 
The aim is to understand the frequency of 209 in 18074245.

Let's proceed to step 1:
The number 209 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 209

Advancing to step 2:
When dividing 18 by 209, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 209

On to step 3:
180 divided by 209 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 180, we get 180.
Fetch the next digit (7) from the dividend, attach it to 180 and continue: 1807 / 209

Step 4:
When dividing 1807 by 209, we get 8 with a remainder of 135.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 135 after subtracting 1672 from 1807.
Bring next digit (4) of the dividend behind the 135 and repeat the process: 1354 / 209

On to step 5:
209 can be fit into 1354 6 times, resulting in a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 1254 from 1354, we get 100.
Take the next digit (2) from the dividend and append it to 100, then repeat: 1002 / 209

Moving on to step 6:
If we divide 1002 by 209, we get 4 and a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 864.0
Subtract 836 from 1002 to get 166.
Append the next digit (4) from the dividend to 166 and continue with: 1664 / 209

Going ahead to step 7:
209 can be fit into 1664 7 times, resulting in a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 8647.0
Subtract 1463 from 1664 to get 201.
Take the next digit (5) from the dividend and append it to 201, then repeat: 2015 / 209

Advancing to step 8:
The number 209 fits into 2015 9 times, leaving a remainder of 134.
Put 9 as the next digit of the answer. 
Result so far: 86479.0
Subtract 1881 from 2015 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
209 can be fit into 1340 6 times, resulting in a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 86479.6
The remainder is 86 after subtracting 1254 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 10:
209 can be fit into 860 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 86479.64
If we subtract 836 from 860, we 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 11:
209 can be fit into 240 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 86479.641
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.

Going ahead to step 12:
209 can be fit into 310 1 times, resulting in a remainder of 101.
The next digit of our result is 1. 
Result so far: 86479.6411
Subtracting 209 from 310 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

In conclusion, the division gives 86479.6411 with a balance of 0.00101.
