Let's divide 91834360 by 66
The aim is to understand the frequency of 66 in 91834360.

Going ahead to step 1:
The number 66 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 66

Going ahead to step 2:
66 goes into 91 1 times with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 91 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 66

Step 3:
If we divide 258 by 66, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 198 from 258 leaves us with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 66

On to step 4:
When dividing 603 by 66, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 594 from 603 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 66

On to step 5:
66 can be fit into 94 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1391.0
Deduct 66 from 94 and we're left with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 66

Advancing to step 6:
If we divide 283 by 66, we get 4 and a remainder of 19.
The next digit of our result is 4. 
Result so far: 13914.0
Subtracting 264 from 283 leaves us with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 66

Step 7:
When dividing 196 by 66, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 139142.0
Subtracting 132 from 196 leaves us with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 66

Going ahead to step 8:
When dividing 640 by 66, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1391429.0
Subtract 594 from 640 to 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.

Going ahead to step 9:
460 divided by 66 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 1391429.6
Subtract 396 from 460 to 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:
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: 1391429.69
Subtract 594 from 640 to 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.

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: 1391429.696
Subtract 396 from 460 to 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.

Advancing to step 12:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 1391429.6969
Subtract 594 from 640 to 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.

Advancing to step 13:
If we divide 460 by 66, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1391429.69696
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.

Let's proceed to step 14:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 1391429.696969
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.

Advancing to step 15:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 1391429.6969696
If we take 396 away from 460, we end up with 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 16:
When dividing 640 by 66, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1391429.69696969
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.

In conclusion, the division gives 1391429.69696969 with a balance of 4.6e-08.
