We look at the division of 730905 by 66 
The aim is to understand the frequency of 66 in 730905.

Moving on to step 1:
7 divided by 66 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 66

Let's proceed to step 2:
The number 66 fits into 73 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 66 from 73, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 66

Going ahead to step 3:
The number 66 fits into 70 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 66 from 70 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 66

On to step 4:
The number 66 fits into 49 0 times, leaving a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we take 0 away from 49, we end up with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 66

Step 5:
When dividing 490 by 66, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 1107.0
The remainder is 28 after subtracting 462 from 490.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 66

Moving on to step 6:
66 can be fit into 285 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 11074.0
Subtracting 264 from 285 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 66 fits into 210 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 11074.3
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 11074.31
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 66, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 11074.318
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 11074.3181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 11074.31818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
120 divided by 66 is 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 11074.318181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 11074.3181818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 66, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 11074.31818181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 11074.31818181 with a remainder of 5.4e-08.
