397607 divided by 20 
Our goal is to divide 397607 by 20.

Let's proceed to step 1:
20 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 20

On to step 2:
39 divided by 20 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 19 after subtracting 20 from 39.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 20

On to step 3:
When dividing 197 by 20, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 180 away from 197, we end up with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 20

Advancing to step 4:
When dividing 176 by 20, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 198.0
If we take 160 away from 176, we end up with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 20

Let's proceed to step 5:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1988.0
The remainder is 0 after subtracting 160 from 160.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 20

Advancing to step 6:
7 divided by 20 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 19880.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
20 goes into 70 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 19880.3
Subtracting 60 from 70 leaves us 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.

Advancing to step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 19880.35
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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19880.35
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.

Going ahead to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19880.35
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 19880.35 with a remainder of 0.0.
