903518 ÷ 20 
We want to divide 903518 by 20.

Going ahead to step 1:
20 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

On to step 2:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 80 from 90 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 20

Step 3:
20 can be fit into 103 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 100 from 103 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 20

Advancing to step 4:
20 goes into 35 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 451.0
Deduct 20 from 35 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 20

Let's proceed to step 5:
151 divided by 20 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 4517.0
Subtracting 140 from 151 leaves us with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 20

Advancing to step 6:
118 divided by 20 is 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 45175.0
If we subtract 100 from 118, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 20, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 45175.9
If we subtract 180 from 180, 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45175.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45175.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 45175.9, and the remainder is 0.0.
