225608 divided by 20 
Let's see how many times 20 fits into 225608.

Advancing to step 1:
20 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 20

Going ahead to step 2:
20 can be fit into 22 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 20 from 22 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 20

Let's proceed to step 3:
25 divided by 20 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 11.0
If we take 20 away from 25, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 20

Going ahead to step 4:
The number 20 fits into 56 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 40 from 56 to get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 20

Moving on to step 5:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1128.0
The remainder is 0 after subtracting 160 from 160.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 20

Step 6:
If we divide 8 by 20, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 11280.0
Deduct 0 from 8 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 can be fit into 80 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 11280.4
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.

Going ahead to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11280.4
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.

Moving on 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: 11280.4
Subtracting 0 from 0 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.

After the division, we end up with 11280.4 and a remainder of 0.0.
