999987 ÷ 1 
Let's see how many times 1 fits into 999987.

On to step 1:
If we divide 9 by 1, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Advancing to step 2:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 9 from 9, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 3:
9 divided by 1 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 999.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Let's proceed to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9999.0
If we take 9 away from 9, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

On to step 5:
If we divide 8 by 1, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 99998.0
If we subtract 8 from 8, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 6:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 999987.0
The remainder is 0 after subtracting 7 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 999987.0
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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 999987.0
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 999987.0, and the remainder is 0.0.
