819980 divided by 1 
Our goal is to divide 819980 by 1.

Let's proceed to step 1:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 2:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 1 from 1 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
Subtract 9 from 9 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 4:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 8199.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Going ahead to step 5:
If we divide 8 by 1, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 81998.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 6:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 819980.0
If we take 0 away from 0, we end up 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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 819980.0
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 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 819980.0
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.

Our division results in 819980.0 with a remaining 0.0.
