87273146 divided by 666 
The aim is to understand the frequency of 666 in 87273146.

Moving on to step 1:
The number 666 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 666

Step 2:
The number 666 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 666

Let's proceed to step 3:
872 divided by 666 is 1 with a remainder of 206.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 666 from 872 leaves us with 206.
Take the next digit (7) from the dividend and append it to 206, then repeat: 2067 / 666

Going ahead to step 4:
When dividing 2067 by 666, we get 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1998 from 2067 to get 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 666

Advancing to step 5:
If we divide 693 by 666, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we subtract 666 from 693, we get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 666

Advancing to step 6:
271 divided by 666 is 0 with a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 1310.0
Subtract 0 from 271 to get 271.
Take the next digit (4) from the dividend and append it to 271, then repeat: 2714 / 666

Going ahead to step 7:
666 goes into 2714 4 times with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 13104.0
If we take 2664 away from 2714, we end up with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 666

Advancing to step 8:
The number 666 fits into 506 0 times, leaving a remainder of 506.
Use 0 as the next digit of our solution. 
Result so far: 131040.0
If we take 0 away from 506, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 9:
The number 666 fits into 5060 7 times, leaving a remainder of 398.
The number 7 becomes the next digit in our result. 
Result so far: 131040.7
The remainder is 398 after subtracting 4662 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 10:
666 can be fit into 3980 5 times, resulting in a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 131040.75
Subtract 3330 from 3980 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 11:
6500 divided by 666 is 9 with a remainder of 506.
Put 9 as the next digit of the answer. 
Result so far: 131040.759
If we subtract 5994 from 6500, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 12:
When dividing 5060 by 666, we get 7 with a remainder of 398.
The number 7 becomes the next digit in our result. 
Result so far: 131040.7597
Subtracting 4662 from 5060 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

On to step 13:
666 can be fit into 3980 5 times, resulting in a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 131040.75975
Subtract 3330 from 3980 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 14:
6500 divided by 666 is 9 with a remainder of 506.
The number 9 becomes the next digit in our result. 
Result so far: 131040.759759
Subtracting 5994 from 6500 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 15:
If we divide 5060 by 666, we get 7 and a remainder of 398.
The number 7 becomes the next digit in our result. 
Result so far: 131040.7597597
Subtracting 4662 from 5060 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 16:
666 goes into 3980 5 times with a remainder of 650.
The next digit of our result is 5. 
Result so far: 131040.75975975
Deduct 3330 from 3980 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.
