We look at the division of 532403 by 20 
Our goal is to divide 532403 by 20.

Advancing to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 20

Advancing to step 2:
53 divided by 20 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 40 away from 53, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 20

Step 3:
When dividing 132 by 20, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 120 from 132 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 20

On to step 4:
124 divided by 20 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
The remainder is 4 after subtracting 120 from 124.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 20

Let's proceed to step 5:
20 goes into 40 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2662.0
Deduct 40 from 40 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 20

Let's proceed to step 6:
20 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 26620.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
20 goes into 30 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 26620.1
The remainder is 10 after subtracting 20 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 26620.15
Deduct 100 from 100 and we're left with 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:
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: 26620.15
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26620.15
Deduct 0 from 0 and we're left with 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 26620.15 and a remainder of 0.0.
