Let's divide 720425 by 90
Our goal is to divide 720425 by 90.

On to step 1:
90 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 90

Let's proceed to step 2:
The number 90 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 90

Step 3:
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: 8.0
Subtract 720 from 720 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 90

Advancing to step 4:
4 divided by 90 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 90

On to step 5:
90 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
If we take 0 away from 42, we end up with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 90

Going ahead to step 6:
90 can be fit into 425 4 times, resulting in a remainder of 65.
Use 4 as the next digit of our solution. 
Result so far: 8004.0
If we subtract 360 from 425, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
The number 90 fits into 650 7 times, leaving a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 8004.7
If we subtract 630 from 650, 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.

Going ahead to step 8:
200 divided by 90 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 8004.72
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.

Advancing to step 9:
90 goes into 200 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 8004.722
Deduct 180 from 200 and we're left 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.

The final result is 8004.722 with a remainder of 0.002.
