67455966 divided by 816 
The aim is to understand the frequency of 816 in 67455966.

Advancing to step 1:
The number 816 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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 816

Moving on to step 2:
The number 816 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 816

On to step 3:
The number 816 fits into 674 0 times, leaving a remainder of 674.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 674 and we're left with 674.
Append the next digit (5) from the dividend to 674 and continue with: 6745 / 816

Advancing to step 4:
The number 816 fits into 6745 8 times, leaving a remainder of 217.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6528 from 6745, we get 217.
Grab the next digit (5) from the dividend, add it to 217, then carry on: 2175 / 816

Let's proceed to step 5:
816 goes into 2175 2 times with a remainder of 543.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtracting 1632 from 2175 leaves us with 543.
Fetch the next digit (9) from the dividend, attach it to 543 and continue: 5439 / 816

Going ahead to step 6:
5439 divided by 816 is 6 with a remainder of 543.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
If we subtract 4896 from 5439, we get 543.
Include the next digit (6) from the dividend after 543, then repeat: 5436 / 816

Moving on to step 7:
816 goes into 5436 6 times with a remainder of 540.
Record the quotient 6 as the next digit in the result. 
Result so far: 8266.0
If we subtract 4896 from 5436, we get 540.
Append the next digit (6) from the dividend to 540 and continue with: 5406 / 816

On to step 8:
If we divide 5406 by 816, we get 6 and a remainder of 510.
The next digit of our result is 6. 
Result so far: 82666.0
If we take 4896 away from 5406, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 9:
816 can be fit into 5100 6 times, resulting in a remainder of 204.
Use 6 as the next digit of our solution. 
Result so far: 82666.6
Deduct 4896 from 5100 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
816 goes into 2040 2 times with a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 82666.62
If we take 1632 away from 2040, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 11:
The number 816 fits into 4080 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 82666.625
Subtracting 4080 from 4080 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
If we divide 0 by 816, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 82666.625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
The number 816 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 82666.625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 82666.625, and the remainder is 0.0.
