We divide 603075 by 12
Let's see how many times 12 fits into 603075.

Advancing to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

Moving on to step 2:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 60 from 60 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Going ahead to step 3:
If we divide 3 by 12, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

On to step 4:
12 goes into 30 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 502.0
If we take 24 away from 30, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 12

Moving on to step 5:
67 divided by 12 is 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5025.0
If we subtract 60 from 67, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 12

On to step 6:
When dividing 75 by 12, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 50256.0
Subtracting 72 from 75 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 50256.2
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 50256.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50256.25
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.

On to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50256.25
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.

The final result is 50256.25 with a remainder of 0.0.
