90339740 divided by 864 
The aim is to understand the frequency of 864 in 90339740.

Advancing to step 1:
The number 864 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 864

Step 2:
The number 864 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 864

Moving on to step 3:
864 can be fit into 903 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 864 from 903 leaves us with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 864

Let's proceed to step 4:
When dividing 393 by 864, we get 0 with a remainder of 393.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 393, we get 393.
Include the next digit (9) from the dividend after 393, then repeat: 3939 / 864

Moving on to step 5:
864 goes into 3939 4 times with a remainder of 483.
Write down 4 as next digit of the result. 
Result so far: 104.0
The remainder is 483 after subtracting 3456 from 3939.
Fetch the next digit (7) from the dividend, attach it to 483 and continue: 4837 / 864

On to step 6:
864 goes into 4837 5 times with a remainder of 517.
The next digit of our result is 5. 
Result so far: 1045.0
The remainder is 517 after subtracting 4320 from 4837.
Bring next digit (4) of the dividend behind the 517 and repeat the process: 5174 / 864

On to step 7:
If we divide 5174 by 864, we get 5 and a remainder of 854.
Record the quotient 5 as the next digit in the result. 
Result so far: 10455.0
Subtracting 4320 from 5174 leaves us with 854.
Append the next digit (0) from the dividend to 854 and continue with: 8540 / 864

Let's proceed to step 8:
864 goes into 8540 9 times with a remainder of 764.
Write down 9 as next digit of the result. 
Result so far: 104559.0
Subtracting 7776 from 8540 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Moving on to step 9:
When dividing 7640 by 864, we get 8 with a remainder of 728.
Record the quotient 8 as the next digit in the result. 
Result so far: 104559.8
The remainder is 728 after subtracting 6912 from 7640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Moving on to step 10:
If we divide 7280 by 864, we get 8 and a remainder of 368.
Record the quotient 8 as the next digit in the result. 
Result so far: 104559.88
If we subtract 6912 from 7280, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 104559.88, with a leftover of 0.368.
