28186251 ÷ 685 
Our goal is to divide 28186251 by 685.

Step 1:
The number 685 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 685

Advancing to step 2:
If we divide 28 by 685, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 685

Let's proceed to step 3:
685 can be fit into 281 0 times, resulting in a remainder of 281.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 281 after subtracting 0 from 281.
Include the next digit (8) from the dividend after 281, then repeat: 2818 / 685

On to step 4:
2818 divided by 685 is 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2740 from 2818, we get 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 685

On to step 5:
685 can be fit into 786 1 times, resulting in a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 685 from 786, we get 101.
Append the next digit (2) from the dividend to 101 and continue with: 1012 / 685

Let's proceed to step 6:
The number 685 fits into 1012 1 times, leaving a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 411.0
Subtract 685 from 1012 to get 327.
Append the next digit (5) from the dividend to 327 and continue with: 3275 / 685

Going ahead to step 7:
685 can be fit into 3275 4 times, resulting in a remainder of 535.
The number 4 becomes the next digit in our result. 
Result so far: 4114.0
If we subtract 2740 from 3275, we get 535.
Grab the next digit (1) from the dividend, add it to 535, then carry on: 5351 / 685

Step 8:
The number 685 fits into 5351 7 times, leaving a remainder of 556.
Write down 7 as next digit of the result. 
Result so far: 41147.0
Subtracting 4795 from 5351 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 9:
If we divide 5560 by 685, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 41147.8
Subtract 5480 from 5560 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
685 can be fit into 800 1 times, resulting in a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 41147.81
Deduct 685 from 800 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
685 goes into 1150 1 times with a remainder of 465.
Record the quotient 1 as the next digit in the result. 
Result so far: 41147.811
Subtracting 685 from 1150 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

The quotient of the division is 41147.811, and the remainder is 0.0465.
