We look at the division of 990384 by 64 
We want to figure out the number of times 990384 can be divided by 64.

Advancing to step 1:
64 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 64

On to step 2:
When dividing 99 by 64, we get 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
If we take 64 away from 99, we end up with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 64

Let's proceed to step 3:
350 divided by 64 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 320 from 350 to get 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 64

Advancing to step 4:
The number 64 fits into 303 4 times, leaving a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 154.0
If we subtract 256 from 303, we get 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 64

Advancing to step 5:
478 divided by 64 is 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 1547.0
Subtracting 448 from 478 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 64

Moving on to step 6:
If we divide 304 by 64, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 15474.0
If we subtract 256 from 304, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
64 goes into 480 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 15474.7
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
64 goes into 320 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15474.75
If we take 320 away from 320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15474.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15474.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15474.75 with a remainder of 0.0.
