We're dividing 748737 by 66 
The aim is to understand the frequency of 66 in 748737.

On to step 1:
If we divide 7 by 66, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 66

Going ahead to step 2:
When dividing 74 by 66, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 66 away from 74, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 66

On to step 3:
The number 66 fits into 88 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 66 from 88, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 66

Step 4:
If we divide 227 by 66, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 198 away from 227, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 66

Moving on to step 5:
66 can be fit into 293 4 times, resulting in a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1134.0
Deduct 264 from 293 and we're left with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 66

Moving on to step 6:
66 goes into 297 4 times with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 11344.0
The remainder is 33 after subtracting 264 from 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
When dividing 330 by 66, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11344.5
Subtract 330 from 330 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 66 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11344.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
66 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11344.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 11344.5 with a balance of 0.0.
