66864980 ÷ 533 
The aim is to understand the frequency of 533 in 66864980.

Advancing to step 1:
533 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 533

Advancing to step 2:
The number 533 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 533

Going ahead to step 3:
The number 533 fits into 668 1 times, leaving a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 533 away from 668, we end up with 135.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 533

On to step 4:
The number 533 fits into 1356 2 times, leaving a remainder of 290.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1066 away from 1356, we end up with 290.
Take the next digit (4) from the dividend and append it to 290, then repeat: 2904 / 533

On to step 5:
If we divide 2904 by 533, we get 5 and a remainder of 239.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 2665 from 2904, we get 239.
Bring next digit (9) of the dividend behind the 239 and repeat the process: 2399 / 533

Going ahead to step 6:
When dividing 2399 by 533, we get 4 with a remainder of 267.
The next digit of our result is 4. 
Result so far: 1254.0
Subtracting 2132 from 2399 leaves us with 267.
Fetch the next digit (8) from the dividend, attach it to 267 and continue: 2678 / 533

Going ahead to step 7:
The number 533 fits into 2678 5 times, leaving a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 12545.0
If we take 2665 away from 2678, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 533

Going ahead to step 8:
When dividing 130 by 533, we get 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 125450.0
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
When dividing 1300 by 533, we get 2 with a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 125450.2
Deduct 1066 from 1300 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 10:
When dividing 2340 by 533, we get 4 with a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 125450.24
Deduct 2132 from 2340 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 11:
The number 533 fits into 2080 3 times, leaving a remainder of 481.
Record the quotient 3 as the next digit in the result. 
Result so far: 125450.243
Deduct 1599 from 2080 and we're left with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

On to step 12:
The number 533 fits into 4810 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 125450.2439
The remainder is 13 after subtracting 4797 from 4810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
533 goes into 130 0 times with a remainder of 130.
The next digit of our result is 0. 
Result so far: 125450.2439
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
When dividing 1300 by 533, we get 2 with a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 125450.243902
Deduct 1066 from 1300 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 15:
If we divide 2340 by 533, we get 4 and a remainder of 208.
The next digit of our result is 4. 
Result so far: 125450.2439024
If we subtract 2132 from 2340, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 16:
533 goes into 2080 3 times with a remainder of 481.
The next digit of our result is 3. 
Result so far: 125450.24390243
The remainder is 481 after subtracting 1599 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

In conclusion, the division gives 125450.24390243 with a balance of 4.81e-07.
