Let's divide 28512436 by 603
We want to divide 28512436 by 603.

Moving on to step 1:
When dividing 2 by 603, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 603

Going ahead to step 2:
603 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 603

Let's proceed to step 3:
If we divide 285 by 603, we get 0 and a remainder of 285.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 285, we end up with 285.
Grab the next digit (1) from the dividend, add it to 285, then carry on: 2851 / 603

Moving on to step 4:
If we divide 2851 by 603, we get 4 and a remainder of 439.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 2412 from 2851, we get 439.
Bring next digit (2) of the dividend behind the 439 and repeat the process: 4392 / 603

Going ahead to step 5:
4392 divided by 603 is 7 with a remainder of 171.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 4221 from 4392, we get 171.
Take the next digit (4) from the dividend and append it to 171, then repeat: 1714 / 603

Step 6:
1714 divided by 603 is 2 with a remainder of 508.
Write down 2 as next digit of the result. 
Result so far: 472.0
If we take 1206 away from 1714, we end up with 508.
Append the next digit (3) from the dividend to 508 and continue with: 5083 / 603

Advancing to step 7:
When dividing 5083 by 603, we get 8 with a remainder of 259.
Write down 8 as next digit of the result. 
Result so far: 4728.0
Deduct 4824 from 5083 and we're left with 259.
Take the next digit (6) from the dividend and append it to 259, then repeat: 2596 / 603

Going ahead to step 8:
603 can be fit into 2596 4 times, resulting in a remainder of 184.
The next digit of our result is 4. 
Result so far: 47284.0
Deduct 2412 from 2596 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
If we divide 1840 by 603, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 47284.3
Deduct 1809 from 1840 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 603 fits into 310 0 times, leaving a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 47284.3
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
603 goes into 3100 5 times with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 47284.305
Subtracting 3015 from 3100 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
If we divide 850 by 603, we get 1 and a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 47284.3051
If we take 603 away from 850, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 13:
The number 603 fits into 2470 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 47284.30514
Deduct 2412 from 2470 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
603 goes into 580 0 times with a remainder of 580.
The next digit of our result is 0. 
Result so far: 47284.30514
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 15:
5800 divided by 603 is 9 with a remainder of 373.
Record the quotient 9 as the next digit in the result. 
Result so far: 47284.3051409
Subtracting 5427 from 5800 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 16:
603 can be fit into 3730 6 times, resulting in a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 47284.30514096
The remainder is 112 after subtracting 3618 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 47284.30514096 with a remainder of 1.12e-07.
