446393 ÷ 66 
The aim is to understand the frequency of 66 in 446393.

Moving on to step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 66

Moving on to step 2:
66 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 66

Advancing to step 3:
If we divide 446 by 66, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 396 from 446, we get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 66

Moving on to step 4:
66 can be fit into 503 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we subtract 462 from 503, we get 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 66

Let's proceed to step 5:
66 can be fit into 419 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 676.0
If we take 396 away from 419, we end up with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 66

On to step 6:
66 goes into 233 3 times with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 6763.0
The remainder is 35 after subtracting 198 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
66 goes into 350 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 6763.5
Subtracting 330 from 350 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 66, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 6763.53
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6763.53
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 66, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 6763.5303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 66 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6763.5303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 6763.530303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
If we divide 20 by 66, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6763.530303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
200 divided by 66 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 6763.53030303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 6763.53030303 with a balance of 2e-09.
