658823 divided by 15 
Our goal is to divide 658823 by 15.

On to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 15

Advancing to step 2:
65 divided by 15 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 5 after subtracting 60 from 65.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 15

On to step 3:
If we divide 58 by 15, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 13 after subtracting 45 from 58.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 15

Let's proceed to step 4:
15 goes into 138 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 439.0
Subtracting 135 from 138 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 15

Advancing to step 5:
When dividing 32 by 15, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 4392.0
Deduct 30 from 32 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 15

Advancing to step 6:
15 can be fit into 23 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 43921.0
If we take 15 away from 23, we end up 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.

On to step 7:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 43921.5
Deduct 75 from 80 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.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 43921.53
If we take 45 away from 50, we end up 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 9:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 43921.533
If we subtract 45 from 50, 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.

Our division results in 43921.533 with a remaining 0.0005.
