We look at the division of 900503 by 53 
Our goal is to divide 900503 by 53.

Advancing to step 1:
When dividing 9 by 53, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 53

On to step 2:
When dividing 90 by 53, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 53 from 90 and we're left with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 53

Moving on to step 3:
If we divide 370 by 53, we get 6 and a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 318 away from 370, we end up with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 53

Let's proceed to step 4:
The number 53 fits into 525 9 times, leaving a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 169.0
Subtract 477 from 525 to get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 53

Step 5:
When dividing 480 by 53, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1699.0
If we subtract 477 from 480, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 53

Moving on to step 6:
The number 53 fits into 33 0 times, leaving a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 16990.0
If we subtract 0 from 33, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
The number 53 fits into 330 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16990.6
If we subtract 318 from 330, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 53 fits into 120 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 16990.62
Subtract 106 from 120 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 53, we get 2 and a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 16990.622
Deduct 106 from 140 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 16990.622 and a remainder of 0.0034.
