39333891 divided by 229 
The aim is to understand the frequency of 229 in 39333891.

Step 1:
3 divided by 229 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 229

Going ahead to step 2:
229 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 229

Moving on to step 3:
229 goes into 393 1 times with a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 229 from 393, we get 164.
Include the next digit (3) from the dividend after 164, then repeat: 1643 / 229

Let's proceed to step 4:
1643 divided by 229 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 40 after subtracting 1603 from 1643.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 229

Advancing to step 5:
When dividing 403 by 229, we get 1 with a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 171.0
If we subtract 229 from 403, we get 174.
Grab the next digit (8) from the dividend, add it to 174, then carry on: 1748 / 229

Let's proceed to step 6:
If we divide 1748 by 229, we get 7 and a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 1717.0
Subtracting 1603 from 1748 leaves us with 145.
Grab the next digit (9) from the dividend, add it to 145, then carry on: 1459 / 229

Let's proceed to step 7:
The number 229 fits into 1459 6 times, leaving a remainder of 85.
The next digit of our result is 6. 
Result so far: 17176.0
Subtracting 1374 from 1459 leaves us with 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 229

Going ahead to step 8:
The number 229 fits into 851 3 times, leaving a remainder of 164.
The next digit of our result is 3. 
Result so far: 171763.0
If we take 687 away from 851, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 9:
1640 divided by 229 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 171763.7
The remainder is 37 after subtracting 1603 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
The number 229 fits into 370 1 times, leaving a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 171763.71
If we subtract 229 from 370, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 11:
229 goes into 1410 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 171763.716
If we subtract 1374 from 1410, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
When dividing 360 by 229, we get 1 with a remainder of 131.
The next digit of our result is 1. 
Result so far: 171763.7161
If we take 229 away from 360, we end up 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 13:
If we divide 1310 by 229, we get 5 and a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 171763.71615
Subtracting 1145 from 1310 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 14:
229 can be fit into 1650 7 times, resulting in a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 171763.716157
Deduct 1603 from 1650 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 15:
470 divided by 229 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 171763.7161572
Subtracting 458 from 470 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 16:
120 divided by 229 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 171763.7161572
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 171763.7161572 with a balance of 1.2e-07.
