We're dividing 42790272 by 603 
We're looking to find how many times 603 goes into 42790272.

Moving on to step 1:
The number 603 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 603

Step 2:
42 divided by 603 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 603

Advancing to step 3:
If we divide 427 by 603, we get 0 and a remainder of 427.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 427, we get 427.
Fetch the next digit (9) from the dividend, attach it to 427 and continue: 4279 / 603

Advancing to step 4:
When dividing 4279 by 603, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 4221 from 4279 to get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 603

On to step 5:
603 can be fit into 580 0 times, resulting in a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
The remainder is 580 after subtracting 0 from 580.
Include the next digit (2) from the dividend after 580, then repeat: 5802 / 603

Let's proceed to step 6:
When dividing 5802 by 603, we get 9 with a remainder of 375.
The number 9 becomes the next digit in our result. 
Result so far: 709.0
Subtracting 5427 from 5802 leaves us with 375.
Grab the next digit (7) from the dividend, add it to 375, then carry on: 3757 / 603

Let's proceed to step 7:
When dividing 3757 by 603, we get 6 with a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 7096.0
If we take 3618 away from 3757, we end up with 139.
Include the next digit (2) from the dividend after 139, then repeat: 1392 / 603

Going ahead to step 8:
1392 divided by 603 is 2 with a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 70962.0
Subtract 1206 from 1392 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 9:
When dividing 1860 by 603, we get 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 70962.3
Deduct 1809 from 1860 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
The number 603 fits into 510 0 times, leaving a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 70962.3
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 11:
When dividing 5100 by 603, we get 8 with a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 70962.308
Deduct 4824 from 5100 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 12:
If we divide 2760 by 603, we get 4 and a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 70962.3084
Subtract 2412 from 2760 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 13:
603 can be fit into 3480 5 times, resulting in a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 70962.30845
If we subtract 3015 from 3480, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 14:
603 goes into 4650 7 times with a remainder of 429.
Put 7 as the next digit of the answer. 
Result so far: 70962.308457
Deduct 4221 from 4650 and we're left with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 15:
When dividing 4290 by 603, we get 7 with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 70962.3084577
Subtract 4221 from 4290 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 70962.3084577 with a remainder of 6.9e-07.
