52342871 divided by 209 
The aim is to understand the frequency of 209 in 52342871.

Moving on to step 1:
When dividing 5 by 209, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 209

On to step 2:
209 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 209

Going ahead to step 3:
209 goes into 523 2 times with a remainder of 105.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 418 from 523 to get 105.
Include the next digit (4) from the dividend after 105, then repeat: 1054 / 209

Advancing to step 4:
When dividing 1054 by 209, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1045 from 1054 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 209

On to step 5:
209 goes into 92 0 times with a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 250.0
If we take 0 away from 92, we end up with 92.
Take the next digit (8) from the dividend and append it to 92, then repeat: 928 / 209

Moving on to step 6:
209 can be fit into 928 4 times, resulting in a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 2504.0
Deduct 836 from 928 and we're left with 92.
Fetch the next digit (7) from the dividend, attach it to 92 and continue: 927 / 209

Step 7:
927 divided by 209 is 4 with a remainder of 91.
The next digit of our result is 4. 
Result so far: 25044.0
If we subtract 836 from 927, we get 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 209

On to step 8:
209 goes into 911 4 times with a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 250444.0
Subtract 836 from 911 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
209 goes into 750 3 times with a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 250444.3
Subtract 627 from 750 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 10:
209 can be fit into 1230 5 times, resulting in a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 250444.35
Subtracting 1045 from 1230 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
209 goes into 1850 8 times with a remainder of 178.
Write down 8 as next digit of the result. 
Result so far: 250444.358
Subtract 1672 from 1850 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 12:
The number 209 fits into 1780 8 times, leaving a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 250444.3588
Subtract 1672 from 1780 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 250444.3588, with a leftover of 0.00108.
