We're dividing 278994 by 25 
Let's see how many times 25 fits into 278994.

Step 1:
2 divided by 25 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 25

Moving on to step 2:
25 goes into 27 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 25 from 27.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 25

Advancing to step 3:
28 divided by 25 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 25 from 28 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 25

Moving on to step 4:
If we divide 39 by 25, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Deduct 25 from 39 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 25

On to step 5:
25 can be fit into 149 5 times, resulting in a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 1115.0
Subtract 125 from 149 to get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 25

Moving on to step 6:
The number 25 fits into 244 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 11159.0
Subtract 225 from 244 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
If we divide 190 by 25, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 11159.7
If we take 175 away from 190, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 11159.76
Deduct 150 from 150 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.

Advancing to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11159.76
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.

On to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11159.76
The remainder is 0 after subtracting 0 from 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 11159.76, with a leftover of 0.0.
