We're dividing 802082 by 90 
We want to divide 802082 by 90.

Step 1:
8 divided by 90 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 90

Moving on to step 2:
The number 90 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 90

Step 3:
If we divide 802 by 90, we get 8 and a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 720 from 802 and we're left with 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 90

Advancing to step 4:
820 divided by 90 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 810 from 820 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 90

Let's proceed to step 5:
90 can be fit into 108 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 891.0
If we take 90 away from 108, we end up with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 90

On to step 6:
When dividing 182 by 90, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 8912.0
Deduct 180 from 182 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 90, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8912.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 8912.02
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 8912.022
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 8912.022 and a remainder of 0.002.
