We look at the division of 934241 by 66 
The aim is to understand the frequency of 66 in 934241.

Advancing to step 1:
66 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 66

On to step 2:
When dividing 93 by 66, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 66 from 93 and we're left with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 66

Advancing to step 3:
274 divided by 66 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 264 from 274 to get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 66

Moving on to step 4:
66 can be fit into 102 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtract 66 from 102 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 66

Advancing to step 5:
The number 66 fits into 364 5 times, leaving a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 1415.0
If we subtract 330 from 364, we get 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 66

Going ahead to step 6:
When dividing 341 by 66, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 14155.0
Subtracting 330 from 341 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 66 fits into 110 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 14155.1
The remainder is 44 after subtracting 66 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
If we divide 440 by 66, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 14155.16
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
If we divide 440 by 66, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 14155.166
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 14155.166 with a remainder of 0.0044.
