1042048 ÷ 864 
We're looking to find how many times 864 goes into 1042048.

Step 1:
If we divide 1 by 864, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 864

Going ahead to step 2:
10 divided by 864 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 864

Let's proceed to step 3:
When dividing 104 by 864, we get 0 with a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 104, we get 104.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 864

Step 4:
864 can be fit into 1042 1 times, resulting in a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 864 from 1042 to get 178.
Grab the next digit (0) from the dividend, add it to 178, then carry on: 1780 / 864

Going ahead to step 5:
864 goes into 1780 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1728 from 1780 to get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 864

Let's proceed to step 6:
The number 864 fits into 524 0 times, leaving a remainder of 524.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 524 leaves us with 524.
Take the next digit (8) from the dividend and append it to 524, then repeat: 5248 / 864

Going ahead to step 7:
When dividing 5248 by 864, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 1206.0
If we take 5184 away from 5248, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
When dividing 640 by 864, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 1206.0
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 9:
The number 864 fits into 6400 7 times, leaving a remainder of 352.
The next digit of our result is 7. 
Result so far: 1206.07
Deduct 6048 from 6400 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 10:
3520 divided by 864 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 1206.074
Subtracting 3456 from 3520 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
640 divided by 864 is 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 1206.074
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 12:
864 can be fit into 6400 7 times, resulting in a remainder of 352.
Use 7 as the next digit of our solution. 
Result so far: 1206.07407
The remainder is 352 after subtracting 6048 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 13:
864 can be fit into 3520 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 1206.074074
Deduct 3456 from 3520 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
864 can be fit into 640 0 times, resulting in a remainder of 640.
The next digit of our result is 0. 
Result so far: 1206.074074
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 15:
The number 864 fits into 6400 7 times, leaving a remainder of 352.
Use 7 as the next digit of our solution. 
Result so far: 1206.07407407
Subtract 6048 from 6400 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 1206.07407407 and a remainder of 3.52e-07.
