30679 ÷ 20 
Let's see how many times 20 fits into 30679.

Step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 20

Going ahead to step 2:
20 goes into 30 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 20 from 30 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 20

Moving on to step 3:
106 divided by 20 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 100 from 106 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 20

Let's proceed to step 4:
67 divided by 20 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
If we subtract 60 from 67, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 20

Going ahead to step 5:
79 divided by 20 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 1533.0
If we take 60 away from 79, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 6:
The number 20 fits into 190 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 1533.9
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1533.95
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.

Advancing to step 8:
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: 1533.95
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1533.95
Deduct 0 from 0 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.

The final result is 1533.95 with a remainder of 0.0.
