We look at the division of 706338 by 66 
The aim is to understand the frequency of 66 in 706338.

Advancing to step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 66

Let's proceed to step 2:
When dividing 70 by 66, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 66 from 70 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 66

Moving on to step 3:
66 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 46 after subtracting 0 from 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 66

On to step 4:
66 goes into 463 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtracting 462 from 463 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 66

Step 5:
66 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 1070.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 66

On to step 6:
The number 66 fits into 138 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 10702.0
Subtract 132 from 138 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
60 divided by 66 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10702.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
If we divide 600 by 66, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 10702.09
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
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: 10702.09
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
600 divided by 66 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 10702.0909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 66 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 10702.0909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 66 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 10702.090909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 66 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10702.090909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
600 divided by 66 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 10702.09090909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 10702.09090909 with a remaining 6e-09.
