81130733 ÷ 664 
The aim is to understand the frequency of 664 in 81130733.

On to step 1:
When dividing 8 by 664, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 664

Moving on to step 2:
81 divided by 664 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 664

Advancing to step 3:
The number 664 fits into 811 1 times, leaving a remainder of 147.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 664 from 811 leaves us with 147.
Append the next digit (3) from the dividend to 147 and continue with: 1473 / 664

Step 4:
When dividing 1473 by 664, we get 2 with a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1328 from 1473 leaves us with 145.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 664

On to step 5:
The number 664 fits into 1450 2 times, leaving a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 1328 from 1450 and we're left with 122.
Bring next digit (7) of the dividend behind the 122 and repeat the process: 1227 / 664

Moving on to step 6:
664 goes into 1227 1 times with a remainder of 563.
Use 1 as the next digit of our solution. 
Result so far: 1221.0
The remainder is 563 after subtracting 664 from 1227.
Bring next digit (3) of the dividend behind the 563 and repeat the process: 5633 / 664

Moving on to step 7:
The number 664 fits into 5633 8 times, leaving a remainder of 321.
Use 8 as the next digit of our solution. 
Result so far: 12218.0
If we subtract 5312 from 5633, we get 321.
Include the next digit (3) from the dividend after 321, then repeat: 3213 / 664

Let's proceed to step 8:
664 goes into 3213 4 times with a remainder of 557.
Write down 4 as next digit of the result. 
Result so far: 122184.0
If we subtract 2656 from 3213, we get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

On to step 9:
664 can be fit into 5570 8 times, resulting in a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 122184.8
Subtract 5312 from 5570 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 10:
When dividing 2580 by 664, we get 3 with a remainder of 588.
Put 3 as the next digit of the answer. 
Result so far: 122184.83
If we take 1992 away from 2580, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 11:
If we divide 5880 by 664, we get 8 and a remainder of 568.
The number 8 becomes the next digit in our result. 
Result so far: 122184.838
Subtracting 5312 from 5880 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 12:
If we divide 5680 by 664, we get 8 and a remainder of 368.
Write down 8 as next digit of the result. 
Result so far: 122184.8388
Subtract 5312 from 5680 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

In conclusion, the division gives 122184.8388 with a balance of 0.00368.
