166203 divided by 5 
We want to figure out the number of times 166203 can be divided by 5.

On to step 1:
When dividing 1 by 5, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 5

Let's proceed to step 2:
5 goes into 16 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 15 away from 16, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 5

On to step 3:
5 goes into 16 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 15 from 16 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 5

Step 4:
12 divided by 5 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 332.0
Subtract 10 from 12 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 5

Advancing to step 5:
If we divide 20 by 5, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 3324.0
If we take 20 away from 20, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 5

On to step 6:
If we divide 3 by 5, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 33240.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 5 fits into 30 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 33240.6
If we subtract 30 from 30, we 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:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 33240.6
Deduct 0 from 0 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.

Let's proceed to step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33240.6
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 final result is 33240.6 with a remainder of 0.0.
