9288489 divided by 864 
Let's see how many times 864 fits into 9288489.

Step 1:
When dividing 9 by 864, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 864

Going ahead to step 2:
The number 864 fits into 92 0 times, leaving a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 92 and we're left with 92.
Include the next digit (8) from the dividend after 92, then repeat: 928 / 864

Advancing to step 3:
864 goes into 928 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 864 from 928 leaves us with 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 864

On to step 4:
When dividing 648 by 864, we get 0 with a remainder of 648.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 648, we end up with 648.
Append the next digit (4) from the dividend to 648 and continue with: 6484 / 864

Moving on to step 5:
If we divide 6484 by 864, we get 7 and a remainder of 436.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we subtract 6048 from 6484, we get 436.
Take the next digit (8) from the dividend and append it to 436, then repeat: 4368 / 864

Advancing to step 6:
The number 864 fits into 4368 5 times, leaving a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 1075.0
The remainder is 48 after subtracting 4320 from 4368.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 864

Advancing to step 7:
If we divide 489 by 864, we get 0 and a remainder of 489.
The number 0 becomes the next digit in our result. 
Result so far: 10750.0
Subtract 0 from 489 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 8:
864 goes into 4890 5 times with a remainder of 570.
Write down 5 as next digit of the result. 
Result so far: 10750.5
Subtracting 4320 from 4890 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 9:
864 can be fit into 5700 6 times, resulting in a remainder of 516.
Record the quotient 6 as the next digit in the result. 
Result so far: 10750.56
Subtracting 5184 from 5700 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 10:
When dividing 5160 by 864, we get 5 with a remainder of 840.
The number 5 becomes the next digit in our result. 
Result so far: 10750.565
Subtract 4320 from 5160 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 11:
864 can be fit into 8400 9 times, resulting in a remainder of 624.
The next digit of our result is 9. 
Result so far: 10750.5659
If we subtract 7776 from 8400, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 12:
When dividing 6240 by 864, we get 7 with a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 10750.56597
If we subtract 6048 from 6240, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 13:
864 goes into 1920 2 times with a remainder of 192.
The next digit of our result is 2. 
Result so far: 10750.565972
If we take 1728 away from 1920, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
1920 divided by 864 is 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 10750.5659722
Deduct 1728 from 1920 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 10750.5659722, and the remainder is 1.92e-06.
