403698 ÷ 15 
Let's see how many times 15 fits into 403698.

Going ahead to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 15

Moving on to step 2:
15 goes into 40 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 30 from 40 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 15

Moving on to step 3:
15 goes into 103 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 90 from 103 and we're left with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 15

Going ahead to step 4:
136 divided by 15 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 269.0
Subtract 135 from 136 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 15

Let's proceed to step 5:
The number 15 fits into 19 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 2691.0
If we subtract 15 from 19, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 15

On to step 6:
48 divided by 15 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 26913.0
The remainder is 3 after subtracting 45 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 26913.2
Subtract 30 from 30 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26913.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26913.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 26913.2, and the remainder is 0.0.
