We look at the division of 203609 by 48 
We want to figure out the number of times 203609 can be divided by 48.

On to step 1:
48 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 48

On to step 2:
20 divided by 48 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 48

Going ahead to step 3:
48 goes into 203 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 192 from 203, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 48

Moving on to step 4:
116 divided by 48 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 20 after subtracting 96 from 116.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 48

On to step 5:
48 can be fit into 200 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 424.0
The remainder is 8 after subtracting 192 from 200.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 48

Let's proceed to step 6:
48 goes into 89 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 4241.0
If we take 48 away from 89, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
The number 48 fits into 410 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 4241.8
If we take 384 away from 410, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
The number 48 fits into 260 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4241.85
The remainder is 20 after subtracting 240 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 48 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4241.854
Subtracting 192 from 200 leaves us 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.

On to step 10:
The number 48 fits into 80 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 4241.8541
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 4241.85416
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
320 divided by 48 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 4241.854166
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 4241.854166 and a remainder of 3.2e-06.
