33661588 divided by 864 
The aim is to understand the frequency of 864 in 33661588.

Let's proceed to step 1:
If we divide 3 by 864, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 864

Going ahead to step 2:
When dividing 33 by 864, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 864

Going ahead to step 3:
336 divided by 864 is 0 with a remainder of 336.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 336 and we're left with 336.
Bring next digit (6) of the dividend behind the 336 and repeat the process: 3366 / 864

Step 4:
If we divide 3366 by 864, we get 3 and a remainder of 774.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2592 from 3366 and we're left with 774.
Bring next digit (1) of the dividend behind the 774 and repeat the process: 7741 / 864

Let's proceed to step 5:
864 can be fit into 7741 8 times, resulting in a remainder of 829.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 6912 from 7741, we get 829.
Grab the next digit (5) from the dividend, add it to 829, then carry on: 8295 / 864

Going ahead to step 6:
If we divide 8295 by 864, we get 9 and a remainder of 519.
The number 9 becomes the next digit in our result. 
Result so far: 389.0
If we subtract 7776 from 8295, we get 519.
Grab the next digit (8) from the dividend, add it to 519, then carry on: 5198 / 864

Moving on to step 7:
If we divide 5198 by 864, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 3896.0
The remainder is 14 after subtracting 5184 from 5198.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 864

Step 8:
864 can be fit into 148 0 times, resulting in a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 38960.0
Deduct 0 from 148 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 9:
If we divide 1480 by 864, we get 1 and a remainder of 616.
The next digit of our result is 1. 
Result so far: 38960.1
The remainder is 616 after subtracting 864 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Advancing to step 10:
The number 864 fits into 6160 7 times, leaving a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 38960.17
Deduct 6048 from 6160 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
1120 divided by 864 is 1 with a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 38960.171
Subtract 864 from 1120 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
864 goes into 2560 2 times with a remainder of 832.
The number 2 becomes the next digit in our result. 
Result so far: 38960.1712
If we take 1728 away from 2560, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 13:
When dividing 8320 by 864, we get 9 with a remainder of 544.
Use 9 as the next digit of our solution. 
Result so far: 38960.17129
Deduct 7776 from 8320 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 14:
If we divide 5440 by 864, we get 6 and a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 38960.171296
Deduct 5184 from 5440 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
864 goes into 2560 2 times with a remainder of 832.
Record the quotient 2 as the next digit in the result. 
Result so far: 38960.1712962
Subtract 1728 from 2560 to get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 16:
If we divide 8320 by 864, we get 9 and a remainder of 544.
Use 9 as the next digit of our solution. 
Result so far: 38960.17129629
If we take 7776 away from 8320, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final result is 38960.17129629 with a remainder of 5.44e-07.
