80609 ÷ 5 
We want to figure out the number of times 80609 can be divided by 5.

Going ahead to step 1:
8 divided by 5 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 8 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 5

On to step 2:
The number 5 fits into 30 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 30 from 30, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 5

Moving on to step 3:
6 divided by 5 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 161.0
The remainder is 1 after subtracting 5 from 6.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 5

Advancing to step 4:
When dividing 10 by 5, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 1612.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 5

Let's proceed to step 5:
9 divided by 5 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 16121.0
Subtract 5 from 9 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 6:
If we divide 40 by 5, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 16121.8
Subtracting 40 from 40 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.

Going ahead to step 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16121.8
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:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16121.8
If we subtract 0 from 0, 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.

The quotient of the division is 16121.8, and the remainder is 0.0.
