We divide 169989 by 10
We're looking to find how many times 10 goes into 169989.

Step 1:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 10

On to step 2:
16 divided by 10 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 10 from 16.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 10

Going ahead to step 3:
10 can be fit into 69 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 9 after subtracting 60 from 69.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 10

Advancing to step 4:
When dividing 99 by 10, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Subtract 90 from 99 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 10

Let's proceed to step 5:
When dividing 98 by 10, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 1699.0
If we take 90 away from 98, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 10

Moving on to step 6:
If we divide 89 by 10, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 16998.0
Subtracting 80 from 89 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 10 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 16998.9
Subtracting 90 from 90 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.

Moving on to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16998.9
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.

Moving on to step 9:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16998.9
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 16998.9, and the remainder is 0.0.
