Let's divide 30850260 by 66
The aim is to understand the frequency of 66 in 30850260.

Moving on to step 1:
66 can be fit into 3 0 times, resulting in 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.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 66

Moving on to step 2:
When dividing 30 by 66, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 66

Moving on to step 3:
308 divided by 66 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 264 from 308 and we're left with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 66

Moving on to step 4:
When dividing 445 by 66, we get 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 396 from 445, we get 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 66

Going ahead to step 5:
If we divide 490 by 66, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 467.0
The remainder is 28 after subtracting 462 from 490.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 66

Moving on to step 6:
If we divide 282 by 66, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4674.0
Subtract 264 from 282 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 66

Let's proceed to step 7:
66 goes into 186 2 times with a remainder of 54.
The next digit of our result is 2. 
Result so far: 46742.0
Subtracting 132 from 186 leaves us with 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 66

Step 8:
When dividing 540 by 66, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 467428.0
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
66 goes into 120 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 467428.1
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 467428.18
If we subtract 528 from 540, we get 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 11:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 467428.181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 467428.1818
Deduct 528 from 540 and we're left 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 13:
If we divide 120 by 66, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 467428.18181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 467428.181818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 467428.1818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 16:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 467428.18181818
Deduct 528 from 540 and we're left 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.

In conclusion, the division gives 467428.18181818 with a balance of 1.2e-08.
