We look at the division of 782090 by 99 
Let's see how many times 99 fits into 782090.

Advancing to step 1:
99 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 99

On to step 2:
The number 99 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 99

Going ahead to step 3:
99 can be fit into 782 7 times, resulting in a remainder of 89.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 693 from 782, we get 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 99

Step 4:
When dividing 890 by 99, we get 8 with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 792 from 890 and we're left with 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 99

Advancing to step 5:
When dividing 989 by 99, we get 9 with a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 789.0
Subtracting 891 from 989 leaves us with 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 99

Going ahead to step 6:
If we divide 980 by 99, we get 9 and a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 7899.0
Deduct 891 from 980 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 7:
890 divided by 99 is 8 with a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 7899.8
Deduct 792 from 890 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 8:
99 can be fit into 980 9 times, resulting in a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 7899.89
Subtract 891 from 980 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
If we divide 890 by 99, we get 8 and a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 7899.898
Subtract 792 from 890 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
99 goes into 980 9 times with a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 7899.8989
Deduct 891 from 980 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
99 goes into 890 8 times with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 7899.89898
If we subtract 792 from 890, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
When dividing 980 by 99, we get 9 with a remainder of 89.
The next digit of our result is 9. 
Result so far: 7899.898989
If we subtract 891 from 980, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 13:
99 can be fit into 890 8 times, resulting in a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 7899.8989898
Deduct 792 from 890 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 14:
If we divide 980 by 99, we get 9 and a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 7899.89898989
If we subtract 891 from 980, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

The final result is 7899.89898989 with a remainder of 8.9e-08.
