81145753 ÷ 229 
The aim is to understand the frequency of 229 in 81145753.

Advancing to step 1:
8 divided by 229 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 229

Advancing to step 2:
If we divide 81 by 229, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 229

Going ahead to step 3:
229 goes into 811 3 times with a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 687 away from 811, we end up with 124.
Take the next digit (4) from the dividend and append it to 124, then repeat: 1244 / 229

Advancing to step 4:
1244 divided by 229 is 5 with a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 1145 away from 1244, we end up with 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 229

Moving on to step 5:
995 divided by 229 is 4 with a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
If we subtract 916 from 995, we get 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 229

Step 6:
When dividing 797 by 229, we get 3 with a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 3543.0
Subtracting 687 from 797 leaves us with 110.
Include the next digit (5) from the dividend after 110, then repeat: 1105 / 229

Let's proceed to step 7:
When dividing 1105 by 229, we get 4 with a remainder of 189.
The number 4 becomes the next digit in our result. 
Result so far: 35434.0
Deduct 916 from 1105 and we're left with 189.
Fetch the next digit (3) from the dividend, attach it to 189 and continue: 1893 / 229

Moving on to step 8:
When dividing 1893 by 229, we get 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 354348.0
Subtracting 1832 from 1893 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
The number 229 fits into 610 2 times, leaving a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 354348.2
Subtract 458 from 610 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
1520 divided by 229 is 6 with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 354348.26
If we subtract 1374 from 1520, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
If we divide 1460 by 229, we get 6 and a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 354348.266
If we subtract 1374 from 1460, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 354348.266 with a remaining 0.0086.
