56456 divided by 15 
We want to figure out the number of times 56456 can be divided by 15.

Going ahead to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 15

Going ahead to step 2:
56 divided by 15 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 11 after subtracting 45 from 56.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 15

Going ahead to step 3:
When dividing 114 by 15, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 37.0
Deduct 105 from 114 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 15

Advancing to step 4:
15 goes into 95 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
The remainder is 5 after subtracting 90 from 95.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 15

Step 5:
When dividing 56 by 15, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3763.0
The remainder is 11 after subtracting 45 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
110 divided by 15 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 3763.7
If we subtract 105 from 110, we 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.

Advancing to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3763.73
Subtracting 45 from 50 leaves us 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.

Advancing to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 3763.733
The remainder is 5 after subtracting 45 from 50.
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 3763.733, and the remainder is 0.0005.
