We look at the division of 52888202 by 239 
The aim is to understand the frequency of 239 in 52888202.

On to step 1:
When dividing 5 by 239, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 239

Advancing to step 2:
If we divide 52 by 239, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 239

On to step 3:
If we divide 528 by 239, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 478 from 528 and we're left with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 239

On to step 4:
When dividing 508 by 239, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 478 from 508 to get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 239

Let's proceed to step 5:
308 divided by 239 is 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtract 239 from 308 to get 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 239

On to step 6:
692 divided by 239 is 2 with a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 2212.0
Subtract 478 from 692 to get 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 239

Step 7:
239 goes into 2140 8 times with a remainder of 228.
Use 8 as the next digit of our solution. 
Result so far: 22128.0
The remainder is 228 after subtracting 1912 from 2140.
Grab the next digit (2) from the dividend, add it to 228, then carry on: 2282 / 239

Moving on to step 8:
2282 divided by 239 is 9 with a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 221289.0
Subtracting 2151 from 2282 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 9:
239 goes into 1310 5 times with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 221289.5
If we subtract 1195 from 1310, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
239 goes into 1150 4 times with a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 221289.54
If we take 956 away from 1150, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 11:
239 goes into 1940 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 221289.548
Subtract 1912 from 1940 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
If we divide 280 by 239, we get 1 and a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 221289.5481
Subtract 239 from 280 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
239 goes into 410 1 times with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 221289.54811
Subtract 239 from 410 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

After the division, we end up with 221289.54811 and a remainder of 0.000171.
