99276864 divided by 576 
We want to figure out the number of times 99276864 can be divided by 576.

Step 1:
When dividing 9 by 576, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 576

Advancing to step 2:
99 divided by 576 is 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 576

Let's proceed to step 3:
992 divided by 576 is 1 with a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 576 from 992 leaves us with 416.
Include the next digit (7) from the dividend after 416, then repeat: 4167 / 576

Step 4:
When dividing 4167 by 576, we get 7 with a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 135 after subtracting 4032 from 4167.
Include the next digit (6) from the dividend after 135, then repeat: 1356 / 576

Let's proceed to step 5:
576 can be fit into 1356 2 times, resulting in a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 1152 from 1356 and we're left with 204.
Fetch the next digit (8) from the dividend, attach it to 204 and continue: 2048 / 576

On to step 6:
2048 divided by 576 is 3 with a remainder of 320.
Write down 3 as next digit of the result. 
Result so far: 1723.0
The remainder is 320 after subtracting 1728 from 2048.
Bring next digit (6) of the dividend behind the 320 and repeat the process: 3206 / 576

Moving on to step 7:
576 can be fit into 3206 5 times, resulting in a remainder of 326.
The number 5 becomes the next digit in our result. 
Result so far: 17235.0
If we subtract 2880 from 3206, we get 326.
Grab the next digit (4) from the dividend, add it to 326, then carry on: 3264 / 576

On to step 8:
When dividing 3264 by 576, we get 5 with a remainder of 384.
The next digit of our result is 5. 
Result so far: 172355.0
If we take 2880 away from 3264, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 9:
If we divide 3840 by 576, we get 6 and a remainder of 384.
The next digit of our result is 6. 
Result so far: 172355.6
Subtracting 3456 from 3840 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
576 can be fit into 3840 6 times, resulting in a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 172355.66
Subtract 3456 from 3840 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 172355.66 with a remainder of 0.384.
