We're dividing 81441031 by 330 
The aim is to understand the frequency of 330 in 81441031.

On to step 1:
If we divide 8 by 330, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 330

Let's proceed to step 2:
If we divide 81 by 330, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 330

Advancing to step 3:
If we divide 814 by 330, we get 2 and a remainder of 154.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 660 away from 814, we end up with 154.
Append the next digit (4) from the dividend to 154 and continue with: 1544 / 330

Let's proceed to step 4:
If we divide 1544 by 330, we get 4 and a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 1320 from 1544 to get 224.
Take the next digit (1) from the dividend and append it to 224, then repeat: 2241 / 330

Step 5:
The number 330 fits into 2241 6 times, leaving a remainder of 261.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Deduct 1980 from 2241 and we're left with 261.
Grab the next digit (0) from the dividend, add it to 261, then carry on: 2610 / 330

Step 6:
2610 divided by 330 is 7 with a remainder of 300.
Record the quotient 7 as the next digit in the result. 
Result so far: 2467.0
If we take 2310 away from 2610, we end up with 300.
Append the next digit (3) from the dividend to 300 and continue with: 3003 / 330

On to step 7:
3003 divided by 330 is 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 24679.0
If we take 2970 away from 3003, we end up with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 330

Advancing to step 8:
When dividing 331 by 330, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 246791.0
Subtract 330 from 331 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 330 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 246791.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
330 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 246791.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 246791.0 with a remaining 0.1.
