Let's divide 903680 by 90
Our goal is to divide 903680 by 90.

Going ahead to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 90

Going ahead to step 2:
90 can be fit into 90 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 90 away from 90, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 90

Advancing to step 3:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 90

Moving on to step 4:
90 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 36, we get 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 90

Advancing to step 5:
368 divided by 90 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
If we subtract 360 from 368, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 90

Step 6:
If we divide 80 by 90, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10040.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 10040.8
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 10040.88
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 10040.88 and a remainder of 0.08.
