We're dividing 28809287 by 666 
The aim is to understand the frequency of 666 in 28809287.

Going ahead to step 1:
666 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 666

Step 2:
If we divide 28 by 666, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 666

Advancing to step 3:
The number 666 fits into 288 0 times, leaving a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 288 leaves us with 288.
Append the next digit (0) from the dividend to 288 and continue with: 2880 / 666

Step 4:
If we divide 2880 by 666, we get 4 and a remainder of 216.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2664 from 2880 to get 216.
Take the next digit (9) from the dividend and append it to 216, then repeat: 2169 / 666

Step 5:
If we divide 2169 by 666, we get 3 and a remainder of 171.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 171 after subtracting 1998 from 2169.
Fetch the next digit (2) from the dividend, attach it to 171 and continue: 1712 / 666

Going ahead to step 6:
If we divide 1712 by 666, we get 2 and a remainder of 380.
Record the quotient 2 as the next digit in the result. 
Result so far: 432.0
Subtracting 1332 from 1712 leaves us with 380.
Include the next digit (8) from the dividend after 380, then repeat: 3808 / 666

Let's proceed to step 7:
If we divide 3808 by 666, we get 5 and a remainder of 478.
Use 5 as the next digit of our solution. 
Result so far: 4325.0
If we take 3330 away from 3808, we end up with 478.
Append the next digit (7) from the dividend to 478 and continue with: 4787 / 666

Moving on to step 8:
4787 divided by 666 is 7 with a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 43257.0
Deduct 4662 from 4787 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
If we divide 1250 by 666, we get 1 and a remainder of 584.
Use 1 as the next digit of our solution. 
Result so far: 43257.1
Subtracting 666 from 1250 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 10:
When dividing 5840 by 666, we get 8 with a remainder of 512.
Write down 8 as next digit of the result. 
Result so far: 43257.18
Subtract 5328 from 5840 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 11:
The number 666 fits into 5120 7 times, leaving a remainder of 458.
Record the quotient 7 as the next digit in the result. 
Result so far: 43257.187
Subtracting 4662 from 5120 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 12:
If we divide 4580 by 666, we get 6 and a remainder of 584.
The next digit of our result is 6. 
Result so far: 43257.1876
The remainder is 584 after subtracting 3996 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 13:
The number 666 fits into 5840 8 times, leaving a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 43257.18768
If we subtract 5328 from 5840, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 14:
If we divide 5120 by 666, we get 7 and a remainder of 458.
The next digit of our result is 7. 
Result so far: 43257.187687
Subtracting 4662 from 5120 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 15:
The number 666 fits into 4580 6 times, leaving a remainder of 584.
The number 6 becomes the next digit in our result. 
Result so far: 43257.1876876
Subtracting 3996 from 4580 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 16:
The number 666 fits into 5840 8 times, leaving a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 43257.18768768
Subtract 5328 from 5840 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

After the division, we end up with 43257.18768768 and a remainder of 5.12e-07.
