816669 divided by 5 
Let's see how many times 5 fits into 816669.

Step 1:
5 goes into 8 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 5

Advancing to step 2:
If we divide 31 by 5, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 30 from 31, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 5

Let's proceed to step 3:
5 can be fit into 16 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Subtracting 15 from 16 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 5

Advancing to step 4:
When dividing 16 by 5, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1633.0
If we take 15 away from 16, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 5

Moving on to step 5:
The number 5 fits into 16 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 16333.0
Subtract 15 from 16 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 5

Advancing to step 6:
5 can be fit into 19 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 163333.0
If we take 15 away from 19, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 5, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 163333.8
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 163333.8
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.

Let's proceed to step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 163333.8
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.

The final outcome is 163333.8, with a leftover of 0.0.
