Let's divide 791442 by 90
We're looking to find how many times 90 goes into 791442.

Moving on to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 90

Moving on to step 2:
If we divide 79 by 90, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 90

Going ahead to step 3:
791 divided by 90 is 8 with a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 720 away from 791, we end up with 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 90

Step 4:
90 can be fit into 714 7 times, resulting in a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 630 away from 714, we end up with 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 90

On to step 5:
844 divided by 90 is 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 879.0
If we take 810 away from 844, we end up with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 90

Going ahead to step 6:
The number 90 fits into 342 3 times, leaving a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 8793.0
If we subtract 270 from 342, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
90 can be fit into 720 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8793.8
Subtract 720 from 720 to 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.

On to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8793.8
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:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8793.8
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.

After the division, we end up with 8793.8 and a remainder of 0.0.
