606476 divided by 66 
The aim is to understand the frequency of 66 in 606476.

Advancing to step 1:
66 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 66

Going ahead to step 2:
When dividing 60 by 66, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 66

Step 3:
When dividing 606 by 66, we get 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 594 from 606, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 66

Advancing to step 4:
If we divide 124 by 66, we get 1 and a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 66 from 124 to get 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 66

Moving on to step 5:
66 can be fit into 587 8 times, resulting in a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 918.0
If we take 528 away from 587, we end up with 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 66

Let's proceed to step 6:
66 goes into 596 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9189.0
If we subtract 594 from 596, 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.

Let's proceed to step 7:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9189.0
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.

Going ahead to step 8:
66 goes into 200 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 9189.03
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.

On to step 9:
66 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9189.03
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.

Going ahead to step 10:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 9189.0303
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.

On to step 11:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 9189.0303
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 12:
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: 9189.030303
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.

Moving on to step 13:
The number 66 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9189.030303
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.

Step 14:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 9189.03030303
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.

The final outcome is 9189.03030303, with a leftover of 2e-09.
