We're dividing 990579 by 64 
We want to figure out the number of times 990579 can be divided by 64.

Step 1:
9 divided by 64 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 64

Let's proceed to step 2:
64 can be fit into 99 1 times, resulting in a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 64 from 99 to get 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 64

Step 3:
64 can be fit into 350 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 320 from 350, we get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 64

Moving on to step 4:
305 divided by 64 is 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 154.0
If we subtract 256 from 305, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 64

On to step 5:
64 goes into 497 7 times with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 1547.0
Subtract 448 from 497 to get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 64

On to step 6:
The number 64 fits into 499 7 times, leaving a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 15477.0
Subtracting 448 from 499 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
When dividing 510 by 64, we get 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 15477.7
The remainder is 62 after subtracting 448 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
The number 64 fits into 620 9 times, leaving a remainder of 44.
The next digit of our result is 9. 
Result so far: 15477.79
If we subtract 576 from 620, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 64 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 15477.796
Subtracting 384 from 440 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 15477.7968
Subtracting 512 from 560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 15477.79687
If we subtract 448 from 480, we 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.

Step 12:
320 divided by 64 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15477.796875
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.

Moving on to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15477.796875
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.

Advancing to step 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15477.796875
Subtracting 0 from 0 leaves us 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.

Our division results in 15477.796875 with a remaining 0.0.
