Let's divide 307228 by 20
Our goal is to divide 307228 by 20.

Advancing to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 20

Step 2:
30 divided by 20 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 20 from 30 to get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 20

Step 3:
If we divide 107 by 20, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 7 after subtracting 100 from 107.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 20

Step 4:
20 goes into 72 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 153.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 20

On to step 5:
20 can be fit into 122 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1536.0
If we subtract 120 from 122, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 20

Moving on to step 6:
28 divided by 20 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 15361.0
Deduct 20 from 28 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
20 goes into 80 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 15361.4
If we take 80 away from 80, 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 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15361.4
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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15361.4
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.

The final outcome is 15361.4, with a leftover of 0.0.
