742805 ÷ 66 
The aim is to understand the frequency of 66 in 742805.

On 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
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 66

Moving on to step 2:
The number 66 fits into 74 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 66 from 74.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 66

Let's proceed to step 3:
The number 66 fits into 82 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 66 from 82 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 66

Advancing to step 4:
The number 66 fits into 168 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtracting 132 from 168 leaves us with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 66

Let's proceed to step 5:
66 goes into 360 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1125.0
If we take 330 away from 360, we end up with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 66

Advancing to step 6:
When dividing 305 by 66, we get 4 with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 11254.0
Subtract 264 from 305 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
66 goes into 410 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 11254.6
Subtracting 396 from 410 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 66, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 11254.62
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 66 fits into 80 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 11254.621
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 66, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11254.6212
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
66 goes into 80 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 11254.62121
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 11254.621212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
66 can be fit into 80 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 11254.6212121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 66 fits into 140 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 11254.62121212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 11254.62121212 with a balance of 8e-09.
