We're dividing 398286 by 33 
The aim is to understand the frequency of 33 in 398286.

Step 1:
3 divided by 33 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 33

Step 2:
If we divide 39 by 33, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 33 from 39.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 33

Advancing to step 3:
33 can be fit into 68 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 66 from 68 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 33

Going ahead to step 4:
If we divide 22 by 33, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 120.0
Subtracting 0 from 22 leaves us with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 33

Going ahead to step 5:
33 can be fit into 228 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 1206.0
Deduct 198 from 228 and we're left with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 33

On to step 6:
33 goes into 306 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 12069.0
Deduct 297 from 306 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 33 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12069.2
The remainder is 24 after subtracting 66 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
If we divide 240 by 33, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 12069.27
Subtract 231 from 240 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
33 goes into 90 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12069.272
The remainder is 24 after subtracting 66 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
33 goes into 240 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 12069.2727
Deduct 231 from 240 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
The number 33 fits into 90 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12069.27272
Subtracting 66 from 90 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
240 divided by 33 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 12069.272727
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
If we divide 90 by 33, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12069.2727272
If we subtract 66 from 90, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 33, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 12069.27272727
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 12069.27272727 with a balance of 9e-09.
