We're dividing 278478 by 17 
We're looking to find how many times 17 goes into 278478.

Moving on to step 1:
The number 17 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 17

Step 2:
17 can be fit into 27 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 17 from 27, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 17

Step 3:
If we divide 108 by 17, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 102 from 108, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 17

Step 4:
64 divided by 17 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we subtract 51 from 64, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 17

On to step 5:
The number 17 fits into 137 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 1638.0
If we take 136 away from 137, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 17

Let's proceed to step 6:
18 divided by 17 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 16381.0
Subtracting 17 from 18 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
17 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16381.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
17 goes into 100 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 16381.05
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 17, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 16381.058
If we subtract 136 from 150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
17 goes into 140 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 16381.0588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 16381.0588, with a leftover of 4e-05.
