263178 ÷ 15 
We want to figure out the number of times 263178 can be divided by 15.

Step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 15

Let's proceed to step 2:
15 goes into 26 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 15 from 26 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 15

Going ahead to step 3:
When dividing 113 by 15, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 105 from 113 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 15

Going ahead to step 4:
If we divide 81 by 15, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Subtracting 75 from 81 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 15

Going ahead to step 5:
67 divided by 15 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 1754.0
Subtracting 60 from 67 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

On to step 6:
15 goes into 78 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 17545.0
Subtracting 75 from 78 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 15 fits into 30 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 17545.2
If we subtract 30 from 30, 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.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17545.2
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.

Moving on to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 17545.2
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 quotient of the division is 17545.2, and the remainder is 0.0.
