We're dividing 3638355 by 315 
Let's see how many times 315 fits into 3638355.

Let's proceed to step 1:
315 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
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 315

Let's proceed to step 2:
315 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 315

Moving on to step 3:
315 can be fit into 363 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 315 from 363 to get 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 315

Moving on to step 4:
488 divided by 315 is 1 with a remainder of 173.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 315 from 488 and we're left with 173.
Bring next digit (3) of the dividend behind the 173 and repeat the process: 1733 / 315

Moving on to step 5:
The number 315 fits into 1733 5 times, leaving a remainder of 158.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtracting 1575 from 1733 leaves us with 158.
Fetch the next digit (5) from the dividend, attach it to 158 and continue: 1585 / 315

Going ahead to step 6:
The number 315 fits into 1585 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1155.0
If we subtract 1575 from 1585, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 315

Step 7:
315 goes into 105 0 times with a remainder of 105.
The next digit of our result is 0. 
Result so far: 11550.0
Subtracting 0 from 105 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 8:
The number 315 fits into 1050 3 times, leaving a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 11550.3
Deduct 945 from 1050 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 9:
1050 divided by 315 is 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 11550.33
If we take 945 away from 1050, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 11550.33 with a remainder of 0.105.
