66794104 divided by 216 
The aim is to understand the frequency of 216 in 66794104.

Step 1:
The number 216 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 216

On to step 2:
216 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 216

Step 3:
The number 216 fits into 667 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 648 from 667 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 216

Going ahead to step 4:
The number 216 fits into 199 0 times, leaving a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 199, we end up with 199.
Bring next digit (4) of the dividend behind the 199 and repeat the process: 1994 / 216

Moving on to step 5:
When dividing 1994 by 216, we get 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Deduct 1944 from 1994 and we're left with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 216

Going ahead to step 6:
216 can be fit into 501 2 times, resulting in a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 3092.0
If we take 432 away from 501, we end up with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 216

Step 7:
If we divide 690 by 216, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 30923.0
Deduct 648 from 690 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 216

Moving on to step 8:
216 can be fit into 424 1 times, resulting in a remainder of 208.
Write down 1 as next digit of the result. 
Result so far: 309231.0
The remainder is 208 after subtracting 216 from 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 9:
216 can be fit into 2080 9 times, resulting in a remainder of 136.
Write down 9 as next digit of the result. 
Result so far: 309231.9
If we subtract 1944 from 2080, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
216 goes into 1360 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 309231.96
Deduct 1296 from 1360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
640 divided by 216 is 2 with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 309231.962
Deduct 432 from 640 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
216 can be fit into 2080 9 times, resulting in a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 309231.9629
Subtract 1944 from 2080 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 13:
216 can be fit into 1360 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 309231.96296
Deduct 1296 from 1360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
The number 216 fits into 640 2 times, leaving a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 309231.962962
Subtract 432 from 640 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 15:
The number 216 fits into 2080 9 times, leaving a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 309231.9629629
If we take 1944 away from 2080, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 16:
216 can be fit into 1360 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 309231.96296296
Subtract 1296 from 1360 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 309231.96296296 with a balance of 6.4e-08.
