807014 ÷ 66 
The aim is to understand the frequency of 66 in 807014.

Let's proceed to step 1:
If we divide 8 by 66, we get 0 and 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.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 66

Going ahead to step 2:
80 divided by 66 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 66 from 80 to get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 66

Step 3:
The number 66 fits into 147 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 132 away from 147, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 66

Moving on to step 4:
When dividing 150 by 66, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 122.0
Deduct 132 from 150 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 66

Step 5:
66 can be fit into 181 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 1222.0
The remainder is 49 after subtracting 132 from 181.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 66

On to step 6:
The number 66 fits into 494 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 12227.0
Subtract 462 from 494 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
If we divide 320 by 66, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 12227.4
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 12227.48
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
320 divided by 66 is 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 12227.484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 12227.4848
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
The number 66 fits into 320 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 12227.48484
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
560 divided by 66 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 12227.484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
66 can be fit into 320 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 12227.4848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
If we divide 560 by 66, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 12227.48484848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 12227.48484848 and a remainder of 3.2e-08.
