169873 ÷ 15 
We want to figure out the number of times 169873 can be divided by 15.

Moving on to step 1:
15 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
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 / 15

On to step 2:
The number 15 fits into 16 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 15 from 16 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 15

Advancing to step 3:
15 can be fit into 19 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 15 from 19 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 15

Let's proceed to step 4:
If we divide 48 by 15, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtract 45 from 48 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 15

Step 5:
When dividing 37 by 15, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 1132.0
The remainder is 7 after subtracting 30 from 37.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 15

On to step 6:
If we divide 73 by 15, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 11324.0
If we take 60 away from 73, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 15 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 11324.8
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 11324.86
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 11324.866
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 11324.866 with a remaining 0.001.
