84087749 ÷ 864 
The aim is to understand the frequency of 864 in 84087749.

Advancing to step 1:
8 divided by 864 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 864

Moving on to step 2:
The number 864 fits into 84 0 times, leaving a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 864

Moving on to step 3:
When dividing 840 by 864, we get 0 with a remainder of 840.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 840 after subtracting 0 from 840.
Include the next digit (8) from the dividend after 840, then repeat: 8408 / 864

Advancing to step 4:
When dividing 8408 by 864, we get 9 with a remainder of 632.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7776 from 8408 to get 632.
Bring next digit (7) of the dividend behind the 632 and repeat the process: 6327 / 864

Advancing to step 5:
6327 divided by 864 is 7 with a remainder of 279.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 279 after subtracting 6048 from 6327.
Include the next digit (7) from the dividend after 279, then repeat: 2797 / 864

On to step 6:
2797 divided by 864 is 3 with a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 973.0
If we take 2592 away from 2797, we end up with 205.
Take the next digit (4) from the dividend and append it to 205, then repeat: 2054 / 864

Step 7:
When dividing 2054 by 864, we get 2 with a remainder of 326.
Write down 2 as next digit of the result. 
Result so far: 9732.0
If we take 1728 away from 2054, we end up with 326.
Fetch the next digit (9) from the dividend, attach it to 326 and continue: 3269 / 864

On to step 8:
864 goes into 3269 3 times with a remainder of 677.
Put 3 as the next digit of the answer. 
Result so far: 97323.0
The remainder is 677 after subtracting 2592 from 3269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Let's proceed to step 9:
864 can be fit into 6770 7 times, resulting in a remainder of 722.
Write down 7 as next digit of the result. 
Result so far: 97323.7
Subtracting 6048 from 6770 leaves us with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 10:
When dividing 7220 by 864, we get 8 with a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 97323.78
Deduct 6912 from 7220 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 11:
If we divide 3080 by 864, we get 3 and a remainder of 488.
Use 3 as the next digit of our solution. 
Result so far: 97323.783
Deduct 2592 from 3080 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
864 can be fit into 4880 5 times, resulting in a remainder of 560.
Write down 5 as next digit of the result. 
Result so far: 97323.7835
Subtract 4320 from 4880 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
5600 divided by 864 is 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 97323.78356
If we take 5184 away from 5600, 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.

On to step 14:
864 goes into 4160 4 times with a remainder of 704.
Write down 4 as next digit of the result. 
Result so far: 97323.783564
The remainder is 704 after subtracting 3456 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 15:
864 goes into 7040 8 times with a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 97323.7835648
If we subtract 6912 from 7040, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 16:
1280 divided by 864 is 1 with a remainder of 416.
The number 1 becomes the next digit in our result. 
Result so far: 97323.78356481
If we subtract 864 from 1280, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The quotient of the division is 97323.78356481, and the remainder is 4.16e-07.
