81288737 ÷ 330 
The aim is to understand the frequency of 330 in 81288737.

Moving on to step 1:
The number 330 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 330

Moving on to step 2:
330 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 330

Advancing to step 3:
812 divided by 330 is 2 with a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 660 from 812 to get 152.
Grab the next digit (8) from the dividend, add it to 152, then carry on: 1528 / 330

On to step 4:
330 goes into 1528 4 times with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 1320 away from 1528, we end up with 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 330

Step 5:
When dividing 2088 by 330, we get 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtract 1980 from 2088 to get 108.
Include the next digit (7) from the dividend after 108, then repeat: 1087 / 330

Let's proceed to step 6:
When dividing 1087 by 330, we get 3 with a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 2463.0
If we take 990 away from 1087, we end up with 97.
Include the next digit (3) from the dividend after 97, then repeat: 973 / 330

Moving on to step 7:
If we divide 973 by 330, we get 2 and a remainder of 313.
Use 2 as the next digit of our solution. 
Result so far: 24632.0
Deduct 660 from 973 and we're left with 313.
Grab the next digit (7) from the dividend, add it to 313, then carry on: 3137 / 330

Let's proceed to step 8:
The number 330 fits into 3137 9 times, leaving a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 246329.0
Subtract 2970 from 3137 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 9:
The number 330 fits into 1670 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 246329.5
If we take 1650 away from 1670, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
330 goes into 200 0 times with a remainder of 200.
The next digit of our result is 0. 
Result so far: 246329.5
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
The number 330 fits into 2000 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 246329.506
Deduct 1980 from 2000 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
330 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 246329.506
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
If we divide 2000 by 330, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 246329.50606
If we take 1980 away from 2000, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
When dividing 200 by 330, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 246329.50606
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
2000 divided by 330 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 246329.5060606
Subtracting 1980 from 2000 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
330 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 246329.5060606
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 246329.5060606 with a balance of 2e-07.
