Let's divide 853120 by 66
The aim is to understand the frequency of 66 in 853120.

Let's proceed to step 1:
66 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 66

On to step 2:
When dividing 85 by 66, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 85 to get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 66

Moving on to step 3:
The number 66 fits into 193 2 times, leaving a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 132 away from 193, we end up with 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 66

Going ahead to step 4:
The number 66 fits into 611 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtracting 594 from 611 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 66

Advancing to step 5:
66 goes into 172 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1292.0
Subtracting 132 from 172 leaves us with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 66

Let's proceed to step 6:
400 divided by 66 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12926.0
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 66 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 12926.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 66 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 12926.06
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
40 divided by 66 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12926.06
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 66 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 12926.0606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
66 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12926.0606
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
66 goes into 400 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 12926.060606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12926.060606
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 66 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 12926.06060606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 12926.06060606 with a balance of 4e-09.
