469890 ÷ 66 
The aim is to understand the frequency of 66 in 469890.

On to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 66

Advancing to step 2:
If we divide 46 by 66, we get 0 and a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 66

Moving on to step 3:
When dividing 469 by 66, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 462 away from 469, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 66

On to step 4:
When dividing 78 by 66, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 12 after subtracting 66 from 78.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 66

On to step 5:
66 can be fit into 129 1 times, resulting in a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 711.0
Subtracting 66 from 129 leaves us with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 66

Advancing to step 6:
66 can be fit into 630 9 times, resulting in a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 7119.0
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
If we divide 360 by 66, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 7119.5
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
66 goes into 300 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7119.54
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 66 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 7119.545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 66, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7119.5454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
When dividing 360 by 66, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 7119.54545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7119.545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
66 goes into 360 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 7119.5454545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 7119.54545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 7119.54545454 with a remaining 3.6e-08.
