Let's divide 388360 by 603
Let's see how many times 603 fits into 388360.

Step 1:
603 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 603

Let's proceed to step 2:
603 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 603

On to step 3:
The number 603 fits into 388 0 times, leaving a remainder of 388.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 388 leaves us with 388.
Fetch the next digit (3) from the dividend, attach it to 388 and continue: 3883 / 603

Let's proceed to step 4:
603 can be fit into 3883 6 times, resulting in a remainder of 265.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 3618 from 3883, we get 265.
Append the next digit (6) from the dividend to 265 and continue with: 2656 / 603

Going ahead to step 5:
603 can be fit into 2656 4 times, resulting in a remainder of 244.
The next digit of our result is 4. 
Result so far: 64.0
If we subtract 2412 from 2656, we get 244.
Fetch the next digit (0) from the dividend, attach it to 244 and continue: 2440 / 603

Step 6:
603 can be fit into 2440 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 644.0
Subtracting 2412 from 2440 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
603 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 644.0
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 8:
2800 divided by 603 is 4 with a remainder of 388.
Put 4 as the next digit of the answer. 
Result so far: 644.04
Subtract 2412 from 2800 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 9:
When dividing 3880 by 603, we get 6 with a remainder of 262.
Put 6 as the next digit of the answer. 
Result so far: 644.046
Subtract 3618 from 3880 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 10:
603 can be fit into 2620 4 times, resulting in a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 644.0464
The remainder is 208 after subtracting 2412 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 11:
2080 divided by 603 is 3 with a remainder of 271.
Write down 3 as next digit of the result. 
Result so far: 644.04643
Deduct 1809 from 2080 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 12:
603 goes into 2710 4 times with a remainder of 298.
The number 4 becomes the next digit in our result. 
Result so far: 644.046434
Subtract 2412 from 2710 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 13:
603 goes into 2980 4 times with a remainder of 568.
Put 4 as the next digit of the answer. 
Result so far: 644.0464344
Deduct 2412 from 2980 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final outcome is 644.0464344, with a leftover of 5.68e-06.
