We're dividing 835284 by 66 
The aim is to understand the frequency of 66 in 835284.

Step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 66

Let's proceed to step 2:
66 goes into 83 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 66 from 83, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 66

Let's proceed to step 3:
66 can be fit into 175 2 times, resulting in a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 132 away from 175, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 66

On to step 4:
When dividing 432 by 66, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 396 from 432 leaves us with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 66

Moving on to step 5:
66 goes into 368 5 times with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 1265.0
If we take 330 away from 368, we end up with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 66

Moving on to step 6:
66 goes into 384 5 times with a remainder of 54.
The next digit of our result is 5. 
Result so far: 12655.0
If we subtract 330 from 384, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
66 goes into 540 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12655.8
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 66, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 12655.81
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
When dividing 540 by 66, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 12655.818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 66 is 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 12655.8181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12655.81818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
120 divided by 66 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 12655.818181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12655.8181818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 12655.81818181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 12655.81818181 with a remainder of 5.4e-08.
