Let's divide 1597 by 66
The aim is to understand the frequency of 66 in 1597.

Going ahead to step 1:
66 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 66

Let's proceed to step 2:
66 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 66

Moving on to step 3:
When dividing 159 by 66, we get 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 27 after subtracting 132 from 159.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 66

Going ahead to step 4:
66 goes into 277 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 264 from 277 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 5:
66 goes into 130 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 24.1
If we subtract 66 from 130, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 6:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 24.19
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
66 goes into 460 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 24.196
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
When dividing 640 by 66, we get 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 24.1969
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 24.19696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 24.196969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
When dividing 460 by 66, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 24.1969696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 24.19696969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 24.19696969 with a balance of 4.6e-08.
