We look at the division of 603779 by 20 
We're looking to find how many times 20 goes into 603779.

Step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 20

On to step 2:
20 goes into 60 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 60 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 20

Moving on to step 3:
When dividing 3 by 20, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 20

On to step 4:
20 goes into 37 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 301.0
Deduct 20 from 37 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 20

Advancing to step 5:
If we divide 177 by 20, we get 8 and a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 3018.0
Deduct 160 from 177 and we're left with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 20

Moving on to step 6:
The number 20 fits into 179 8 times, leaving a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 30188.0
Subtract 160 from 179 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 30188.9
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 30188.95
If we subtract 100 from 100, 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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30188.95
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.

Advancing to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30188.95
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.

The final result is 30188.95 with a remainder of 0.0.
