We divide 1245595 by 603
Our goal is to divide 1245595 by 603.

Going ahead to step 1:
If we divide 1 by 603, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 603

Moving on to step 2:
If we divide 12 by 603, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 603

Moving on to step 3:
603 can be fit into 124 0 times, resulting in a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 124 to get 124.
Grab the next digit (5) from the dividend, add it to 124, then carry on: 1245 / 603

Let's proceed to step 4:
603 goes into 1245 2 times with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1206 from 1245, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 603

On to step 5:
603 can be fit into 395 0 times, resulting in a remainder of 395.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 395 and we're left with 395.
Include the next digit (9) from the dividend after 395, then repeat: 3959 / 603

Let's proceed to step 6:
The number 603 fits into 3959 6 times, leaving a remainder of 341.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Deduct 3618 from 3959 and we're left with 341.
Append the next digit (5) from the dividend to 341 and continue with: 3415 / 603

Step 7:
603 goes into 3415 5 times with a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 2065.0
If we take 3015 away from 3415, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 8:
If we divide 4000 by 603, we get 6 and a remainder of 382.
Record the quotient 6 as the next digit in the result. 
Result so far: 2065.6
Deduct 3618 from 4000 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 9:
The number 603 fits into 3820 6 times, leaving a remainder of 202.
Record the quotient 6 as the next digit in the result. 
Result so far: 2065.66
Subtracting 3618 from 3820 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final outcome is 2065.66, with a leftover of 0.202.
