Let's divide 278493 by 1
We're looking to find how many times 1 goes into 278493.

Advancing to step 1:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Advancing to step 2:
If we divide 7 by 1, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 7 from 7, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

On to step 3:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 278.0
If we take 8 away from 8, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Moving on to step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2784.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

On to step 5:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 27849.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Moving on to step 6:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 278493.0
Subtracting 3 from 3 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 278493.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 278493.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 278493.0 with a remainder of 0.0.
