24218712 ÷ 209 
The aim is to understand the frequency of 209 in 24218712.

Going ahead to step 1:
When dividing 2 by 209, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 209

Let's proceed to step 2:
When dividing 24 by 209, we get 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 209

Going ahead to step 3:
209 goes into 242 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 209 from 242 to get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 209

Moving on to step 4:
209 can be fit into 331 1 times, resulting in a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 122 after subtracting 209 from 331.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 209

Going ahead to step 5:
The number 209 fits into 1228 5 times, leaving a remainder of 183.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtracting 1045 from 1228 leaves us with 183.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 209

Let's proceed to step 6:
The number 209 fits into 1837 8 times, leaving a remainder of 165.
The next digit of our result is 8. 
Result so far: 1158.0
The remainder is 165 after subtracting 1672 from 1837.
Bring next digit (1) of the dividend behind the 165 and repeat the process: 1651 / 209

Moving on to step 7:
1651 divided by 209 is 7 with a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 11587.0
If we take 1463 away from 1651, we end up with 188.
Fetch the next digit (2) from the dividend, attach it to 188 and continue: 1882 / 209

Let's proceed to step 8:
209 goes into 1882 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 115879.0
Subtract 1881 from 1882 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
209 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 115879.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 209 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 115879.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 115879.0 and a remainder of 0.1.
