We look at the division of 78949135 by 603 
Let's see how many times 603 fits into 78949135.

Step 1:
603 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 603

On to step 2:
603 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 603

Going ahead to step 3:
789 divided by 603 is 1 with a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 186 after subtracting 603 from 789.
Fetch the next digit (4) from the dividend, attach it to 186 and continue: 1864 / 603

Moving on to step 4:
603 can be fit into 1864 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1809 away from 1864, we end up with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 603

Advancing to step 5:
603 can be fit into 559 0 times, resulting in a remainder of 559.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 559 leaves us with 559.
Append the next digit (1) from the dividend to 559 and continue with: 5591 / 603

Moving on to step 6:
603 goes into 5591 9 times with a remainder of 164.
Write down 9 as next digit of the result. 
Result so far: 1309.0
If we take 5427 away from 5591, we end up with 164.
Fetch the next digit (3) from the dividend, attach it to 164 and continue: 1643 / 603

Going ahead to step 7:
603 goes into 1643 2 times with a remainder of 437.
Put 2 as the next digit of the answer. 
Result so far: 13092.0
If we subtract 1206 from 1643, we get 437.
Take the next digit (5) from the dividend and append it to 437, then repeat: 4375 / 603

Let's proceed to step 8:
603 can be fit into 4375 7 times, resulting in a remainder of 154.
The next digit of our result is 7. 
Result so far: 130927.0
Subtract 4221 from 4375 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
1540 divided by 603 is 2 with a remainder of 334.
Write down 2 as next digit of the result. 
Result so far: 130927.2
If we take 1206 away from 1540, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 10:
The number 603 fits into 3340 5 times, leaving a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 130927.25
Subtract 3015 from 3340 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
3250 divided by 603 is 5 with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 130927.255
The remainder is 235 after subtracting 3015 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

After the division, we end up with 130927.255 and a remainder of 0.0235.
