We're dividing 606543 by 20 
We want to figure out the number of times 606543 can be divided by 20.

Step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 20

Advancing to step 2:
20 can be fit into 60 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 60 away from 60, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 20

Let's proceed to step 3:
When dividing 6 by 20, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 20

Let's proceed to step 4:
The number 20 fits into 65 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 303.0
Subtracting 60 from 65 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 20

On to step 5:
The number 20 fits into 54 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 3032.0
If we subtract 40 from 54, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 20

Advancing to step 6:
When dividing 143 by 20, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 30327.0
Subtract 140 from 143 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 30327.1
Subtract 20 from 30 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 30327.15
The remainder is 0 after subtracting 100 from 100.
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30327.15
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.

Moving on to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30327.15
Subtracting 0 from 0 leaves us 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 30327.15 and a remainder of 0.0.
