We're dividing 308122 by 20 
We want to figure out the number of times 308122 can be divided by 20.

Going ahead to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 20

Step 2:
The number 20 fits into 30 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 20 from 30 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 20

Moving on to step 3:
The number 20 fits into 108 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 100 away from 108, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 20

Advancing to step 4:
81 divided by 20 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 80 from 81 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 20

Advancing to step 5:
When dividing 12 by 20, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 1540.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 20

Going ahead to step 6:
The number 20 fits into 122 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 15406.0
If we take 120 away from 122, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 20 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 15406.1
Subtracting 20 from 20 leaves us 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15406.1
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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15406.1
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.

After the division, we end up with 15406.1 and a remainder of 0.0.
