410258 divided by 66 
The aim is to understand the frequency of 66 in 410258.

Let's proceed to step 1:
4 divided by 66 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 66

Going ahead to step 2:
41 divided by 66 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 66

Step 3:
66 can be fit into 410 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 396 away from 410, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 66

Moving on to step 4:
142 divided by 66 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 132 from 142 and we're left with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 66

Moving on to step 5:
105 divided by 66 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 621.0
Deduct 66 from 105 and we're left with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 66

Going ahead to step 6:
398 divided by 66 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6216.0
Subtract 396 from 398 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.

Advancing to step 7:
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: 6216.0
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.

Going ahead to step 8:
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: 6216.03
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 9:
20 divided by 66 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6216.03
Deduct 0 from 20 and we're left 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.

Let's proceed to step 10:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 6216.0303
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.

Moving on to step 11:
20 divided by 66 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6216.0303
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 12:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 6216.030303
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.

On to step 13:
20 divided by 66 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6216.030303
If we take 0 away from 20, we end up 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 14:
If we divide 200 by 66, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 6216.03030303
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.

The final result is 6216.03030303 with a remainder of 2e-09.
