We look at the division of 31152429 by 864 
The aim is to understand the frequency of 864 in 31152429.

Advancing to step 1:
If we divide 3 by 864, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 864

On to step 2:
864 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 864

Moving on to step 3:
The number 864 fits into 311 0 times, leaving a remainder of 311.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 311, we get 311.
Fetch the next digit (5) from the dividend, attach it to 311 and continue: 3115 / 864

Going ahead to step 4:
864 can be fit into 3115 3 times, resulting in a remainder of 523.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2592 from 3115 to get 523.
Bring next digit (2) of the dividend behind the 523 and repeat the process: 5232 / 864

Moving on to step 5:
864 can be fit into 5232 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 5184 from 5232 leaves us with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 864

Advancing to step 6:
864 goes into 484 0 times with a remainder of 484.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
If we take 0 away from 484, we end up with 484.
Bring next digit (2) of the dividend behind the 484 and repeat the process: 4842 / 864

On to step 7:
When dividing 4842 by 864, we get 5 with a remainder of 522.
Write down 5 as next digit of the result. 
Result so far: 3605.0
Subtracting 4320 from 4842 leaves us with 522.
Take the next digit (9) from the dividend and append it to 522, then repeat: 5229 / 864

Advancing to step 8:
864 goes into 5229 6 times with a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 36056.0
The remainder is 45 after subtracting 5184 from 5229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
450 divided by 864 is 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 36056.0
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
When dividing 4500 by 864, we get 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 36056.05
Deduct 4320 from 4500 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
1800 divided by 864 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 36056.052
Subtract 1728 from 1800 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
864 goes into 720 0 times with a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 36056.052
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 13:
The number 864 fits into 7200 8 times, leaving a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 36056.05208
If we take 6912 away from 7200, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 14:
2880 divided by 864 is 3 with a remainder of 288.
The number 3 becomes the next digit in our result. 
Result so far: 36056.052083
If we take 2592 away from 2880, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
864 can be fit into 2880 3 times, resulting in a remainder of 288.
Put 3 as the next digit of the answer. 
Result so far: 36056.0520833
Subtract 2592 from 2880 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 36056.0520833 with a remainder of 2.88e-06.
