2750450 ÷ 864 
We're looking to find how many times 864 goes into 2750450.

Advancing to step 1:
2 divided by 864 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 864

Going ahead to step 2:
If we divide 27 by 864, we get 0 and a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 864

Going ahead to step 3:
The number 864 fits into 275 0 times, leaving a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 275 to get 275.
Fetch the next digit (0) from the dividend, attach it to 275 and continue: 2750 / 864

Step 4:
864 can be fit into 2750 3 times, resulting in a remainder of 158.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2592 away from 2750, we end up with 158.
Bring next digit (4) of the dividend behind the 158 and repeat the process: 1584 / 864

On to step 5:
1584 divided by 864 is 1 with a remainder of 720.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 864 from 1584 to get 720.
Include the next digit (5) from the dividend after 720, then repeat: 7205 / 864

Moving on to step 6:
When dividing 7205 by 864, we get 8 with a remainder of 293.
Write down 8 as next digit of the result. 
Result so far: 318.0
Subtract 6912 from 7205 to get 293.
Grab the next digit (0) from the dividend, add it to 293, then carry on: 2930 / 864

On to step 7:
The number 864 fits into 2930 3 times, leaving a remainder of 338.
Write down 3 as next digit of the result. 
Result so far: 3183.0
Deduct 2592 from 2930 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 8:
When dividing 3380 by 864, we get 3 with a remainder of 788.
Use 3 as the next digit of our solution. 
Result so far: 3183.3
Subtract 2592 from 3380 to get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Moving on to step 9:
The number 864 fits into 7880 9 times, leaving a remainder of 104.
The number 9 becomes the next digit in our result. 
Result so far: 3183.39
Deduct 7776 from 7880 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
When dividing 1040 by 864, we get 1 with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 3183.391
If we take 864 away from 1040, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 11:
The number 864 fits into 1760 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 3183.3912
The remainder is 32 after subtracting 1728 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
When dividing 320 by 864, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 3183.3912
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
The number 864 fits into 3200 3 times, leaving a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 3183.391203
The remainder is 608 after subtracting 2592 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 14:
When dividing 6080 by 864, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 3183.3912037
Deduct 6048 from 6080 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
864 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 3183.3912037
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 3183.3912037, with a leftover of 3.2e-07.
