66473466 ÷ 331 
The aim is to understand the frequency of 331 in 66473466.

Advancing to step 1:
331 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 331

Advancing to step 2:
If we divide 66 by 331, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 331

Moving on to step 3:
The number 331 fits into 664 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 662 from 664 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 331

Going ahead to step 4:
27 divided by 331 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 27 to get 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 331

Advancing to step 5:
When dividing 273 by 331, we get 0 with a remainder of 273.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Subtract 0 from 273 to get 273.
Grab the next digit (4) from the dividend, add it to 273, then carry on: 2734 / 331

Going ahead to step 6:
331 goes into 2734 8 times with a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 2008.0
If we take 2648 away from 2734, we end up with 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 331

On to step 7:
The number 331 fits into 866 2 times, leaving a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 20082.0
Subtract 662 from 866 to get 204.
Bring next digit (6) of the dividend behind the 204 and repeat the process: 2046 / 331

Step 8:
If we divide 2046 by 331, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 200826.0
If we subtract 1986 from 2046, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 331, we get 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 200826.1
Subtract 331 from 600 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 10:
331 goes into 2690 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 200826.18
Subtract 2648 from 2690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
If we divide 420 by 331, we get 1 and a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 200826.181
Deduct 331 from 420 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 12:
The number 331 fits into 890 2 times, leaving a remainder of 228.
The next digit of our result is 2. 
Result so far: 200826.1812
Subtract 662 from 890 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 13:
331 goes into 2280 6 times with a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 200826.18126
Deduct 1986 from 2280 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 14:
If we divide 2940 by 331, we get 8 and a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 200826.181268
Deduct 2648 from 2940 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 15:
2920 divided by 331 is 8 with a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 200826.1812688
Subtract 2648 from 2920 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 200826.1812688 and a remainder of 2.72e-06.
