We look at the division of 42750862 by 603 
Our goal is to divide 42750862 by 603.

Let's proceed to step 1:
The number 603 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 603

Step 2:
When dividing 42 by 603, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 603

Step 3:
If we divide 427 by 603, we get 0 and a remainder of 427.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 427 to get 427.
Fetch the next digit (5) from the dividend, attach it to 427 and continue: 4275 / 603

Step 4:
4275 divided by 603 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4221 from 4275, we get 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 603

Step 5:
When dividing 540 by 603, we get 0 with a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtracting 0 from 540 leaves us with 540.
Bring next digit (8) of the dividend behind the 540 and repeat the process: 5408 / 603

Advancing to step 6:
If we divide 5408 by 603, we get 8 and a remainder of 584.
Use 8 as the next digit of our solution. 
Result so far: 708.0
The remainder is 584 after subtracting 4824 from 5408.
Include the next digit (6) from the dividend after 584, then repeat: 5846 / 603

Moving on to step 7:
5846 divided by 603 is 9 with a remainder of 419.
The next digit of our result is 9. 
Result so far: 7089.0
The remainder is 419 after subtracting 5427 from 5846.
Include the next digit (2) from the dividend after 419, then repeat: 4192 / 603

Step 8:
When dividing 4192 by 603, we get 6 with a remainder of 574.
Record the quotient 6 as the next digit in the result. 
Result so far: 70896.0
If we subtract 3618 from 4192, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 9:
603 can be fit into 5740 9 times, resulting in a remainder of 313.
Use 9 as the next digit of our solution. 
Result so far: 70896.9
If we take 5427 away from 5740, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 10:
If we divide 3130 by 603, we get 5 and a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 70896.95
Deduct 3015 from 3130 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
603 can be fit into 1150 1 times, resulting in a remainder of 547.
Put 1 as the next digit of the answer. 
Result so far: 70896.951
The remainder is 547 after subtracting 603 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 12:
603 can be fit into 5470 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 70896.9519
Deduct 5427 from 5470 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
If we divide 430 by 603, we get 0 and a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 70896.9519
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 14:
The number 603 fits into 4300 7 times, leaving a remainder of 79.
The next digit of our result is 7. 
Result so far: 70896.951907
Subtract 4221 from 4300 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 15:
603 can be fit into 790 1 times, resulting in a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 70896.9519071
If we take 603 away from 790, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 16:
When dividing 1870 by 603, we get 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 70896.95190713
If we take 1809 away from 1870, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 70896.95190713, with a leftover of 6.1e-08.
