67998 ÷ 20 
Let's see how many times 20 fits into 67998.

On to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 20

Advancing to step 2:
If we divide 67 by 20, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 67 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 20

Going ahead to step 3:
The number 20 fits into 79 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 60 from 79 and we're left with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 20

Step 4:
20 can be fit into 199 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 339.0
Subtracting 180 from 199 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 20

Step 5:
198 divided by 20 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 3399.0
If we subtract 180 from 198, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 6:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3399.9
If we take 180 away from 180, we end up 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.

Advancing to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3399.9
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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3399.9
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.

After the division, we end up with 3399.9 and a remainder of 0.0.
