We're dividing 662411 by 66 
The aim is to understand the frequency of 66 in 662411.

Step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 66

On to step 2:
66 goes into 66 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 66 from 66 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 66

Advancing to step 3:
2 divided by 66 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 66

Let's proceed to step 4:
66 can be fit into 24 0 times, resulting in a remainder of 24.
The next digit of our result is 0. 
Result so far: 100.0
The remainder is 24 after subtracting 0 from 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 66

Going ahead to step 5:
66 goes into 241 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 1003.0
If we take 198 away from 241, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 66

On to step 6:
If we divide 431 by 66, we get 6 and a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 10036.0
Subtract 396 from 431 to get 35.
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:
350 divided by 66 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10036.5
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.

Step 8:
The number 66 fits into 200 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 10036.53
Subtracting 198 from 200 leaves us 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.

Step 9:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10036.53
The remainder is 20 after subtracting 0 from 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 10:
If we divide 200 by 66, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 10036.5303
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.

Let's proceed to step 11:
20 divided by 66 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10036.5303
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.

Moving on to step 12:
200 divided by 66 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 10036.530303
Deduct 198 from 200 and we're left 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:
20 divided by 66 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10036.530303
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.

Let's proceed to step 14:
When dividing 200 by 66, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 10036.53030303
Subtracting 198 from 200 leaves us 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.

Our division results in 10036.53030303 with a remaining 2e-09.
