15865692 ÷ 506 
Our goal is to divide 15865692 by 506.

Going ahead to step 1:
506 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 506

Moving on to step 2:
If we divide 15 by 506, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 506

Advancing to step 3:
When dividing 158 by 506, we get 0 with a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Fetch the next digit (6) from the dividend, attach it to 158 and continue: 1586 / 506

Step 4:
When dividing 1586 by 506, we get 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1518 from 1586 leaves us with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 506

Step 5:
The number 506 fits into 685 1 times, leaving a remainder of 179.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 506 away from 685, we end up with 179.
Bring next digit (6) of the dividend behind the 179 and repeat the process: 1796 / 506

Moving on to step 6:
506 can be fit into 1796 3 times, resulting in a remainder of 278.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Subtract 1518 from 1796 to get 278.
Bring next digit (9) of the dividend behind the 278 and repeat the process: 2789 / 506

Moving on to step 7:
If we divide 2789 by 506, we get 5 and a remainder of 259.
The next digit of our result is 5. 
Result so far: 3135.0
The remainder is 259 after subtracting 2530 from 2789.
Bring next digit (2) of the dividend behind the 259 and repeat the process: 2592 / 506

Let's proceed to step 8:
If we divide 2592 by 506, we get 5 and a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 31355.0
If we subtract 2530 from 2592, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
When dividing 620 by 506, we get 1 with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 31355.1
Deduct 506 from 620 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
If we divide 1140 by 506, we get 2 and a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 31355.12
Deduct 1012 from 1140 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
The number 506 fits into 1280 2 times, leaving a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 31355.122
Deduct 1012 from 1280 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The quotient of the division is 31355.122, and the remainder is 0.0268.
