53161205 ÷ 239 
The aim is to understand the frequency of 239 in 53161205.

Step 1:
The number 239 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 239

Let's proceed to step 2:
239 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 239

Let's proceed to step 3:
239 can be fit into 531 2 times, resulting in a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 478 from 531, we get 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 239

Advancing to step 4:
536 divided by 239 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 478 from 536 to get 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 239

Advancing to step 5:
239 can be fit into 581 2 times, resulting in a remainder of 103.
Put 2 as the next digit of the answer. 
Result so far: 222.0
Deduct 478 from 581 and we're left with 103.
Include the next digit (2) from the dividend after 103, then repeat: 1032 / 239

Advancing to step 6:
When dividing 1032 by 239, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 2224.0
Subtract 956 from 1032 to get 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 239

Moving on to step 7:
When dividing 760 by 239, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 22243.0
Subtract 717 from 760 to get 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 239

Let's proceed to step 8:
When dividing 435 by 239, we get 1 with a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 222431.0
Subtracting 239 from 435 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 9:
When dividing 1960 by 239, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 222431.8
The remainder is 48 after subtracting 1912 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
239 can be fit into 480 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 222431.82
The remainder is 2 after subtracting 478 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
239 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 222431.82
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 239, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 222431.82
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 222431.82 with a remaining 0.002.
