We're dividing 12293278 by 1 
Let's see how many times 1 fits into 12293278.

Step 1:
1 divided by 1 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Advancing to step 2:
2 divided by 1 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Step 3:
2 divided by 1 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 122.0
If we subtract 2 from 2, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Advancing to step 4:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1229.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

On to step 5:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 12293.0
If we take 3 away from 3, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

On to step 6:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 122932.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Advancing to step 7:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 1229327.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 8:
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: 12293278.0
Subtract 8 from 8 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12293278.0
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 10:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12293278.0
Subtract 0 from 0 to get 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 outcome is 12293278.0, with a leftover of 0.0.
