We're dividing 66323569 by 955 
The aim is to understand the frequency of 955 in 66323569.

Step 1:
If we divide 6 by 955, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 955

Step 2:
955 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 955

Going ahead to step 3:
When dividing 663 by 955, we get 0 with a remainder of 663.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 663, we get 663.
Append the next digit (2) from the dividend to 663 and continue with: 6632 / 955

Moving on to step 4:
The number 955 fits into 6632 6 times, leaving a remainder of 902.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5730 from 6632 to get 902.
Append the next digit (3) from the dividend to 902 and continue with: 9023 / 955

On to step 5:
If we divide 9023 by 955, we get 9 and a remainder of 428.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 8595 from 9023 leaves us with 428.
Include the next digit (5) from the dividend after 428, then repeat: 4285 / 955

Step 6:
If we divide 4285 by 955, we get 4 and a remainder of 465.
Use 4 as the next digit of our solution. 
Result so far: 694.0
Deduct 3820 from 4285 and we're left with 465.
Fetch the next digit (6) from the dividend, attach it to 465 and continue: 4656 / 955

Advancing to step 7:
If we divide 4656 by 955, we get 4 and a remainder of 836.
The number 4 becomes the next digit in our result. 
Result so far: 6944.0
If we take 3820 away from 4656, we end up with 836.
Fetch the next digit (9) from the dividend, attach it to 836 and continue: 8369 / 955

Let's proceed to step 8:
The number 955 fits into 8369 8 times, leaving a remainder of 729.
Write down 8 as next digit of the result. 
Result so far: 69448.0
Subtract 7640 from 8369 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Going ahead to step 9:
955 goes into 7290 7 times with a remainder of 605.
The number 7 becomes the next digit in our result. 
Result so far: 69448.7
The remainder is 605 after subtracting 6685 from 7290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 10:
955 goes into 6050 6 times with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 69448.76
If we take 5730 away from 6050, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
955 goes into 3200 3 times with a remainder of 335.
Write down 3 as next digit of the result. 
Result so far: 69448.763
Subtract 2865 from 3200 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 12:
When dividing 3350 by 955, we get 3 with a remainder of 485.
The next digit of our result is 3. 
Result so far: 69448.7633
Deduct 2865 from 3350 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

In conclusion, the division gives 69448.7633 with a balance of 0.00485.
