We divide 77520098 by 330
The aim is to understand the frequency of 330 in 77520098.

Advancing to step 1:
7 divided by 330 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 330

Advancing to step 2:
77 divided by 330 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 330

Moving on to step 3:
330 can be fit into 775 2 times, resulting in a remainder of 115.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 660 from 775, we get 115.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 330

Let's proceed to step 4:
If we divide 1152 by 330, we get 3 and a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 990 from 1152 and we're left with 162.
Grab the next digit (0) from the dividend, add it to 162, then carry on: 1620 / 330

Going ahead to step 5:
When dividing 1620 by 330, we get 4 with a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Deduct 1320 from 1620 and we're left with 300.
Fetch the next digit (0) from the dividend, attach it to 300 and continue: 3000 / 330

Let's proceed to step 6:
When dividing 3000 by 330, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 2349.0
If we take 2970 away from 3000, we end up with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 330

Let's proceed to step 7:
The number 330 fits into 309 0 times, leaving a remainder of 309.
The next digit of our result is 0. 
Result so far: 23490.0
If we subtract 0 from 309, we get 309.
Append the next digit (8) from the dividend to 309 and continue with: 3098 / 330

Moving on to step 8:
330 can be fit into 3098 9 times, resulting in a remainder of 128.
The next digit of our result is 9. 
Result so far: 234909.0
Subtracting 2970 from 3098 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
If we divide 1280 by 330, we get 3 and a remainder of 290.
Put 3 as the next digit of the answer. 
Result so far: 234909.3
If we subtract 990 from 1280, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
If we divide 2900 by 330, we get 8 and a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 234909.38
If we take 2640 away from 2900, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
The number 330 fits into 2600 7 times, leaving a remainder of 290.
Record the quotient 7 as the next digit in the result. 
Result so far: 234909.387
Subtract 2310 from 2600 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 12:
2900 divided by 330 is 8 with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 234909.3878
If we subtract 2640 from 2900, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
The number 330 fits into 2600 7 times, leaving a remainder of 290.
The next digit of our result is 7. 
Result so far: 234909.38787
Subtracting 2310 from 2600 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
330 goes into 2900 8 times with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 234909.387878
Subtract 2640 from 2900 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 15:
2600 divided by 330 is 7 with a remainder of 290.
The next digit of our result is 7. 
Result so far: 234909.3878787
Subtract 2310 from 2600 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 16:
When dividing 2900 by 330, we get 8 with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 234909.38787878
Subtract 2640 from 2900 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 234909.38787878 and a remainder of 2.6e-07.
