278692 ÷ 15 
We want to divide 278692 by 15.

Advancing to step 1:
If we divide 2 by 15, we get 0 and 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 / 15

Advancing to step 2:
27 divided by 15 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 15 from 27 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 15

Going ahead to step 3:
15 goes into 128 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 120 from 128, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 15

Advancing to step 4:
15 goes into 86 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Deduct 75 from 86 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 15

Step 5:
When dividing 119 by 15, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1857.0
Deduct 105 from 119 and we're left with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 15

Moving on to step 6:
If we divide 142 by 15, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 18579.0
Deduct 135 from 142 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 18579.4
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 18579.46
The remainder is 10 after subtracting 90 from 100.
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 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 18579.466
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 18579.466, with a leftover of 0.001.
