We're dividing 757059 by 66 
The aim is to understand the frequency of 66 in 757059.

Step 1:
66 goes into 7 0 times 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.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 66

Going ahead to step 2:
66 goes into 75 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 66 from 75 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 66

On to step 3:
When dividing 97 by 66, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 66 from 97 to get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 66

Advancing to step 4:
310 divided by 66 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 114.0
The remainder is 46 after subtracting 264 from 310.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 66

Let's proceed to step 5:
If we divide 465 by 66, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1147.0
The remainder is 3 after subtracting 462 from 465.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 66

Advancing to step 6:
66 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 11470.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
If we divide 390 by 66, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
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.

Let's proceed to step 8:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 11470.59
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.

Step 9:
66 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11470.59
Subtracting 0 from 60 leaves us 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.

Moving on to step 10:
If we divide 600 by 66, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 11470.5909
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 11:
When dividing 60 by 66, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11470.5909
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.

Going ahead to step 12:
66 goes into 600 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 11470.590909
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.

Advancing 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
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.

Going ahead to step 14:
When dividing 600 by 66, we get 9 with 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 quotient of the division is 11470.59090909, and the remainder is 6e-09.
