We're dividing 485774 by 15 
Let's see how many times 15 fits into 485774.

Moving on to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 15

Moving on to step 2:
15 goes into 48 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 45 away from 48, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 15

Advancing to step 3:
35 divided by 15 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 30 from 35 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 15

Step 4:
15 can be fit into 57 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 323.0
Deduct 45 from 57 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 15

Advancing to step 5:
If we divide 127 by 15, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 3238.0
If we subtract 120 from 127, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 15

Let's proceed to step 6:
The number 15 fits into 74 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 32384.0
Subtracting 60 from 74 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.

Advancing to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 32384.9
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.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 32384.93
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.

Let's proceed to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 32384.933
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.

The final result is 32384.933 with a remainder of 0.0005.
