We're dividing 811649 by 15 
We're looking to find how many times 15 goes into 811649.

Let's proceed to step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 15

Moving on to step 2:
15 goes into 81 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 75 from 81, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 15

Step 3:
15 can be fit into 61 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 60 from 61, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 15

Let's proceed to step 4:
16 divided by 15 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 541.0
Deduct 15 from 16 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 15

On to step 5:
The number 15 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 5410.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 15

Going ahead to step 6:
The number 15 fits into 149 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 54109.0
Subtracting 135 from 149 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 54109.9
Subtracting 135 from 140 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.

Going ahead to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 54109.93
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.

Let's proceed to step 9:
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: 54109.933
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 54109.933 with a remaining 0.0005.
