8006436 ÷ 864 
Let's see how many times 864 fits into 8006436.

Let's proceed to step 1:
8 divided by 864 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 864

Advancing to step 2:
80 divided by 864 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 864

Let's proceed to step 3:
864 can be fit into 800 0 times, resulting in a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 800 to get 800.
Include the next digit (6) from the dividend after 800, then repeat: 8006 / 864

Let's proceed to step 4:
The number 864 fits into 8006 9 times, leaving a remainder of 230.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7776 from 8006, we get 230.
Fetch the next digit (4) from the dividend, attach it to 230 and continue: 2304 / 864

Let's proceed to step 5:
864 goes into 2304 2 times with a remainder of 576.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Deduct 1728 from 2304 and we're left with 576.
Take the next digit (3) from the dividend and append it to 576, then repeat: 5763 / 864

On to step 6:
The number 864 fits into 5763 6 times, leaving a remainder of 579.
The next digit of our result is 6. 
Result so far: 926.0
Subtract 5184 from 5763 to get 579.
Include the next digit (6) from the dividend after 579, then repeat: 5796 / 864

On to step 7:
864 can be fit into 5796 6 times, resulting in a remainder of 612.
Write down 6 as next digit of the result. 
Result so far: 9266.0
Subtract 5184 from 5796 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 8:
If we divide 6120 by 864, we get 7 and a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 9266.7
If we take 6048 away from 6120, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
864 goes into 720 0 times with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 9266.7
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 10:
7200 divided by 864 is 8 with a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 9266.708
Deduct 6912 from 7200 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 11:
If we divide 2880 by 864, we get 3 and a remainder of 288.
The number 3 becomes the next digit in our result. 
Result so far: 9266.7083
If we subtract 2592 from 2880, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 12:
2880 divided by 864 is 3 with a remainder of 288.
The next digit of our result is 3. 
Result so far: 9266.70833
If we take 2592 away from 2880, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 9266.70833, with a leftover of 0.000288.
