We're dividing 2644944 by 864 
Let's see how many times 864 fits into 2644944.

Advancing to step 1:
When dividing 2 by 864, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 864

Let's proceed to step 2:
26 divided by 864 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 864

Going ahead to step 3:
The number 864 fits into 264 0 times, leaving a remainder of 264.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 264 and we're left with 264.
Include the next digit (4) from the dividend after 264, then repeat: 2644 / 864

On to step 4:
When dividing 2644 by 864, we get 3 with a remainder of 52.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2592 from 2644 to get 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 864

Moving on to step 5:
864 can be fit into 529 0 times, resulting in a remainder of 529.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 529 leaves us with 529.
Take the next digit (4) from the dividend and append it to 529, then repeat: 5294 / 864

Moving on to step 6:
The number 864 fits into 5294 6 times, leaving a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
Deduct 5184 from 5294 and we're left with 110.
Include the next digit (4) from the dividend after 110, then repeat: 1104 / 864

On to step 7:
864 can be fit into 1104 1 times, resulting in a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 3061.0
The remainder is 240 after subtracting 864 from 1104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 8:
The number 864 fits into 2400 2 times, leaving a remainder of 672.
Record the quotient 2 as the next digit in the result. 
Result so far: 3061.2
Subtract 1728 from 2400 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 9:
The number 864 fits into 6720 7 times, leaving a remainder of 672.
The number 7 becomes the next digit in our result. 
Result so far: 3061.27
Subtract 6048 from 6720 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 10:
When dividing 6720 by 864, we get 7 with a remainder of 672.
Use 7 as the next digit of our solution. 
Result so far: 3061.277
Subtracting 6048 from 6720 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Our division results in 3061.277 with a remaining 0.0672.
