We look at the division of 757059 by 66 
The aim is to understand the frequency of 66 in 757059.

Let's proceed 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.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 66

Advancing to step 2:
75 divided by 66 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 66 from 75.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 66

On to step 3:
66 can be fit into 97 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 31 after subtracting 66 from 97.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 66

Going ahead to step 4:
66 can be fit into 310 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 264 away from 310, we end up with 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 66

Step 5:
66 goes into 465 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1147.0
Subtract 462 from 465 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 66

Going ahead to step 6:
If we divide 39 by 66, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 11470.0
Subtracting 0 from 39 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 66 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 11470.5
If we take 330 away from 390, 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.

On to step 8:
600 divided by 66 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 11470.59
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.

Step 9:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11470.59
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 10:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 11470.5909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 66, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 11470.5909
If we subtract 0 from 60, we get 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:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 11470.590909
If we subtract 594 from 600, we 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.

Let's proceed to 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: 11470.590909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 11470.59090909
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.

The final outcome is 11470.59090909, with a leftover of 6e-09.
