We divide 903464 by 20
We want to figure out the number of times 903464 can be divided by 20.

On to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Moving on to step 2:
90 divided by 20 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 80 from 90 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 20

Step 3:
20 can be fit into 103 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 100 from 103 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 20

Let's proceed to step 4:
20 goes into 34 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 451.0
The remainder is 14 after subtracting 20 from 34.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 20

Advancing to step 5:
20 can be fit into 146 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 4517.0
If we subtract 140 from 146, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 20

Step 6:
The number 20 fits into 64 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 45173.0
Subtracting 60 from 64 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 45173.2
If we subtract 40 from 40, 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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45173.2
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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45173.2
Subtract 0 from 0 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.

After the division, we end up with 45173.2 and a remainder of 0.0.
