We're dividing 337568 by 20 
Let's see how many times 20 fits into 337568.

Moving on to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 20

Moving on to step 2:
When dividing 33 by 20, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 20 from 33.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 20

On to step 3:
The number 20 fits into 137 6 times, leaving a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 120 from 137 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 20

Step 4:
The number 20 fits into 175 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 168.0
Subtracting 160 from 175 leaves us with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 20

Step 5:
20 can be fit into 156 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1687.0
The remainder is 16 after subtracting 140 from 156.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 20

Let's proceed to step 6:
The number 20 fits into 168 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 16878.0
If we subtract 160 from 168, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 20, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 16878.4
Deduct 80 from 80 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16878.4
Subtract 0 from 0 to 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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16878.4
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.

Our division results in 16878.4 with a remaining 0.0.
