30124559 ÷ 864 
The aim is to understand the frequency of 864 in 30124559.

Moving on to step 1:
864 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 864

On to step 2:
30 divided by 864 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 864

On to step 3:
When dividing 301 by 864, we get 0 with a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 301 to get 301.
Take the next digit (2) from the dividend and append it to 301, then repeat: 3012 / 864

Moving on to step 4:
When dividing 3012 by 864, we get 3 with a remainder of 420.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2592 from 3012 and we're left with 420.
Take the next digit (4) from the dividend and append it to 420, then repeat: 4204 / 864

Advancing to step 5:
The number 864 fits into 4204 4 times, leaving a remainder of 748.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 748 after subtracting 3456 from 4204.
Include the next digit (5) from the dividend after 748, then repeat: 7485 / 864

On to step 6:
When dividing 7485 by 864, we get 8 with a remainder of 573.
Write down 8 as next digit of the result. 
Result so far: 348.0
The remainder is 573 after subtracting 6912 from 7485.
Take the next digit (5) from the dividend and append it to 573, then repeat: 5735 / 864

Moving on to step 7:
864 can be fit into 5735 6 times, resulting in a remainder of 551.
Record the quotient 6 as the next digit in the result. 
Result so far: 3486.0
If we subtract 5184 from 5735, we get 551.
Fetch the next digit (9) from the dividend, attach it to 551 and continue: 5519 / 864

Advancing to step 8:
If we divide 5519 by 864, we get 6 and a remainder of 335.
The next digit of our result is 6. 
Result so far: 34866.0
Subtracting 5184 from 5519 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 9:
If we divide 3350 by 864, we get 3 and a remainder of 758.
Put 3 as the next digit of the answer. 
Result so far: 34866.3
If we subtract 2592 from 3350, we get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Advancing to step 10:
864 goes into 7580 8 times with a remainder of 668.
The next digit of our result is 8. 
Result so far: 34866.38
The remainder is 668 after subtracting 6912 from 7580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

On to step 11:
864 goes into 6680 7 times with a remainder of 632.
The number 7 becomes the next digit in our result. 
Result so far: 34866.387
If we subtract 6048 from 6680, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 12:
864 can be fit into 6320 7 times, resulting in a remainder of 272.
The next digit of our result is 7. 
Result so far: 34866.3877
If we take 6048 away from 6320, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 34866.3877 and a remainder of 0.00272.
