21331203 ÷ 229 
The aim is to understand the frequency of 229 in 21331203.

Step 1:
229 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 229

On to step 2:
229 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 229

Going ahead to step 3:
229 can be fit into 213 0 times, resulting in a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 229

On to step 4:
When dividing 2133 by 229, we get 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 2061 away from 2133, we end up with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 229

Let's proceed to step 5:
229 goes into 721 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtracting 687 from 721 leaves us with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 229

Let's proceed to step 6:
229 goes into 342 1 times with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 931.0
If we take 229 away from 342, we end up with 113.
Include the next digit (0) from the dividend after 113, then repeat: 1130 / 229

Advancing to step 7:
229 goes into 1130 4 times with a remainder of 214.
The next digit of our result is 4. 
Result so far: 9314.0
Subtract 916 from 1130 to get 214.
Append the next digit (3) from the dividend to 214 and continue with: 2143 / 229

Advancing to step 8:
229 goes into 2143 9 times with a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 93149.0
If we subtract 2061 from 2143, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
The number 229 fits into 820 3 times, leaving a remainder of 133.
Write down 3 as next digit of the result. 
Result so far: 93149.3
If we subtract 687 from 820, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 10:
When dividing 1330 by 229, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 93149.35
If we take 1145 away from 1330, we end up 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:
229 goes into 1850 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 93149.358
Deduct 1832 from 1850 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
229 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 93149.358
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 13:
If we divide 1800 by 229, we get 7 and a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 93149.35807
If we take 1603 away from 1800, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 14:
229 goes into 1970 8 times with a remainder of 138.
Use 8 as the next digit of our solution. 
Result so far: 93149.358078
Deduct 1832 from 1970 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 15:
The number 229 fits into 1380 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 93149.3580786
If we take 1374 away from 1380, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 16:
60 divided by 229 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 93149.3580786
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 93149.3580786 with a remaining 6e-08.
