86012992 ÷ 728 
The aim is to understand the frequency of 728 in 86012992.

On to step 1:
If we divide 8 by 728, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 728

On to step 2:
When dividing 86 by 728, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 728

On to step 3:
If we divide 860 by 728, we get 1 and a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 728 from 860, we get 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 728

Step 4:
The number 728 fits into 1321 1 times, leaving a remainder of 593.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 728 from 1321 leaves us with 593.
Fetch the next digit (2) from the dividend, attach it to 593 and continue: 5932 / 728

Let's proceed to step 5:
728 can be fit into 5932 8 times, resulting in a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtracting 5824 from 5932 leaves us with 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 728

Let's proceed to step 6:
728 goes into 1089 1 times with a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 1181.0
The remainder is 361 after subtracting 728 from 1089.
Bring next digit (9) of the dividend behind the 361 and repeat the process: 3619 / 728

Let's proceed to step 7:
The number 728 fits into 3619 4 times, leaving a remainder of 707.
The next digit of our result is 4. 
Result so far: 11814.0
If we take 2912 away from 3619, we end up with 707.
Include the next digit (2) from the dividend after 707, then repeat: 7072 / 728

Advancing to step 8:
728 can be fit into 7072 9 times, resulting in a remainder of 520.
Record the quotient 9 as the next digit in the result. 
Result so far: 118149.0
Deduct 6552 from 7072 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 9:
The number 728 fits into 5200 7 times, leaving a remainder of 104.
Record the quotient 7 as the next digit in the result. 
Result so far: 118149.7
The remainder is 104 after subtracting 5096 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
728 can be fit into 1040 1 times, resulting in a remainder of 312.
The next digit of our result is 1. 
Result so far: 118149.71
The remainder is 312 after subtracting 728 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 11:
728 goes into 3120 4 times with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 118149.714
The remainder is 208 after subtracting 2912 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
If we divide 2080 by 728, we get 2 and a remainder of 624.
Use 2 as the next digit of our solution. 
Result so far: 118149.7142
Subtracting 1456 from 2080 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 13:
728 goes into 6240 8 times with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 118149.71428
If we take 5824 away from 6240, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
728 can be fit into 4160 5 times, resulting in a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 118149.714285
If we take 3640 away from 4160, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 15:
5200 divided by 728 is 7 with a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 118149.7142857
Subtract 5096 from 5200 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
When dividing 1040 by 728, we get 1 with a remainder of 312.
Record the quotient 1 as the next digit in the result. 
Result so far: 118149.71428571
If we subtract 728 from 1040, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

After the division, we end up with 118149.71428571 and a remainder of 3.12e-07.
