We divide 9505964 by 666
The aim is to understand the frequency of 666 in 9505964.

Let's proceed to step 1:
If we divide 9 by 666, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 666

Step 2:
95 divided by 666 is 0 with a remainder of 95.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 95 after subtracting 0 from 95.
Include the next digit (0) from the dividend after 95, then repeat: 950 / 666

Step 3:
950 divided by 666 is 1 with a remainder of 284.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 666 from 950 and we're left with 284.
Include the next digit (5) from the dividend after 284, then repeat: 2845 / 666

Moving on to step 4:
666 goes into 2845 4 times with a remainder of 181.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2664 from 2845 and we're left with 181.
Take the next digit (9) from the dividend and append it to 181, then repeat: 1819 / 666

Moving on to step 5:
If we divide 1819 by 666, we get 2 and a remainder of 487.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Subtract 1332 from 1819 to get 487.
Include the next digit (6) from the dividend after 487, then repeat: 4876 / 666

On to step 6:
The number 666 fits into 4876 7 times, leaving a remainder of 214.
The next digit of our result is 7. 
Result so far: 1427.0
The remainder is 214 after subtracting 4662 from 4876.
Grab the next digit (4) from the dividend, add it to 214, then carry on: 2144 / 666

On to step 7:
The number 666 fits into 2144 3 times, leaving a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 14273.0
Subtracting 1998 from 2144 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 8:
666 goes into 1460 2 times with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 14273.2
Deduct 1332 from 1460 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
666 goes into 1280 1 times with a remainder of 614.
Write down 1 as next digit of the result. 
Result so far: 14273.21
If we subtract 666 from 1280, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 10:
6140 divided by 666 is 9 with a remainder of 146.
The next digit of our result is 9. 
Result so far: 14273.219
Subtracting 5994 from 6140 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 11:
666 goes into 1460 2 times with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 14273.2192
If we subtract 1332 from 1460, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
666 can be fit into 1280 1 times, resulting in a remainder of 614.
The next digit of our result is 1. 
Result so far: 14273.21921
If we subtract 666 from 1280, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 13:
When dividing 6140 by 666, we get 9 with a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 14273.219219
Deduct 5994 from 6140 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 14:
If we divide 1460 by 666, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 14273.2192192
Subtracting 1332 from 1460 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
The number 666 fits into 1280 1 times, leaving a remainder of 614.
Put 1 as the next digit of the answer. 
Result so far: 14273.21921921
Subtract 666 from 1280 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The final outcome is 14273.21921921, with a leftover of 6.14e-07.
