689976 ÷ 15 
Our goal is to divide 689976 by 15.

Step 1:
6 divided by 15 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 15

Going ahead to step 2:
68 divided by 15 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 8 after subtracting 60 from 68.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 15

Going ahead to step 3:
89 divided by 15 is 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 14 after subtracting 75 from 89.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 15

Going ahead to step 4:
When dividing 149 by 15, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Subtract 135 from 149 to get 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 15

Moving on to step 5:
147 divided by 15 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 4599.0
Subtract 135 from 147 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 15

Let's proceed to step 6:
The number 15 fits into 126 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 45998.0
If we take 120 away from 126, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 15 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 45998.4
Deduct 60 from 60 and we're left 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 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45998.4
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.

On to step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45998.4
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 45998.4, and the remainder is 0.0.
