264353 divided by 15 
Let's see how many times 15 fits into 264353.

Advancing to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 15

Step 2:
15 goes into 26 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 15 from 26 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 15

Moving on to step 3:
114 divided by 15 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 105 from 114 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 15

Moving on to step 4:
The number 15 fits into 93 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
Subtract 90 from 93 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 15

Moving on to step 5:
If we divide 35 by 15, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 1762.0
If we subtract 30 from 35, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 15

On to step 6:
If we divide 53 by 15, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 17623.0
Subtracting 45 from 53 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
15 goes into 80 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 17623.5
The remainder is 5 after subtracting 75 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 17623.53
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 17623.533
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 17623.533, and the remainder is 0.0005.
