Let's divide 18900571 by 229
The aim is to understand the frequency of 229 in 18900571.

On to step 1:
The number 229 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 229

Advancing to step 2:
18 divided by 229 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 229

On to step 3:
If we divide 189 by 229, we get 0 and a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 189 after subtracting 0 from 189.
Bring next digit (0) of the dividend behind the 189 and repeat the process: 1890 / 229

On to step 4:
The number 229 fits into 1890 8 times, leaving a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 1832 from 1890 leaves us with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 229

Moving on to step 5:
229 goes into 580 2 times with a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtracting 458 from 580 leaves us with 122.
Bring next digit (5) of the dividend behind the 122 and repeat the process: 1225 / 229

Advancing to step 6:
229 goes into 1225 5 times with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 825.0
Subtract 1145 from 1225 to get 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 229

Let's proceed to step 7:
229 can be fit into 807 3 times, resulting in a remainder of 120.
Record the quotient 3 as the next digit in the result. 
Result so far: 8253.0
If we take 687 away from 807, we end up with 120.
Fetch the next digit (1) from the dividend, attach it to 120 and continue: 1201 / 229

Moving on to step 8:
The number 229 fits into 1201 5 times, leaving a remainder of 56.
The next digit of our result is 5. 
Result so far: 82535.0
If we subtract 1145 from 1201, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
The number 229 fits into 560 2 times, leaving a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 82535.2
The remainder is 102 after subtracting 458 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 10:
When dividing 1020 by 229, we get 4 with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 82535.24
The remainder is 104 after subtracting 916 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
The number 229 fits into 1040 4 times, leaving a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 82535.244
The remainder is 124 after subtracting 916 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Our division results in 82535.244 with a remaining 0.0124.
