We divide 124278 by 10
We want to figure out the number of times 124278 can be divided by 10.

Advancing to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 10

On to step 2:
When dividing 12 by 10, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 10 from 12 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 10

Step 3:
10 goes into 24 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 4 after subtracting 20 from 24.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 10

On to step 4:
42 divided by 10 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 124.0
Deduct 40 from 42 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 10

Step 5:
When dividing 27 by 10, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 1242.0
Deduct 20 from 27 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 10

On to step 6:
78 divided by 10 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 12427.0
The remainder is 8 after subtracting 70 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 10 fits into 80 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 12427.8
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12427.8
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.

Going ahead to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12427.8
If we subtract 0 from 0, we 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 result is 12427.8 with a remainder of 0.0.
