Let's divide 13825155 by 229
The aim is to understand the frequency of 229 in 13825155.

Advancing to step 1:
The number 229 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 229

Step 2:
When dividing 13 by 229, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 229

Moving on to step 3:
If we divide 138 by 229, we get 0 and a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 138 and we're left with 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 229

Let's proceed to step 4:
229 can be fit into 1382 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 1374 from 1382 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 229

Step 5:
229 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 229

Advancing to step 6:
229 can be fit into 851 3 times, resulting in a remainder of 164.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
If we subtract 687 from 851, we get 164.
Grab the next digit (5) from the dividend, add it to 164, then carry on: 1645 / 229

Step 7:
229 can be fit into 1645 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 6037.0
The remainder is 42 after subtracting 1603 from 1645.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 229

On to step 8:
If we divide 425 by 229, we get 1 and a remainder of 196.
The number 1 becomes the next digit in our result. 
Result so far: 60371.0
If we subtract 229 from 425, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 9:
229 can be fit into 1960 8 times, resulting in a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 60371.8
If we subtract 1832 from 1960, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 10:
If we divide 1280 by 229, we get 5 and a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 60371.85
Subtract 1145 from 1280 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 11:
The number 229 fits into 1350 5 times, leaving a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 60371.855
If we take 1145 away from 1350, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 60371.855 and a remainder of 0.0205.
