We look at the division of 11253138 by 603 
We want to figure out the number of times 11253138 can be divided by 603.

Let's proceed to step 1:
When dividing 1 by 603, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 603

Moving on to step 2:
The number 603 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 603

Going ahead to step 3:
603 goes into 112 0 times with a remainder of 112.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 112 leaves us with 112.
Take the next digit (5) from the dividend and append it to 112, then repeat: 1125 / 603

Step 4:
1125 divided by 603 is 1 with a remainder of 522.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 603 from 1125 and we're left with 522.
Bring next digit (3) of the dividend behind the 522 and repeat the process: 5223 / 603

Advancing to step 5:
When dividing 5223 by 603, we get 8 with a remainder of 399.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 4824 from 5223, we get 399.
Append the next digit (1) from the dividend to 399 and continue with: 3991 / 603

Step 6:
3991 divided by 603 is 6 with a remainder of 373.
The next digit of our result is 6. 
Result so far: 186.0
If we subtract 3618 from 3991, we get 373.
Include the next digit (3) from the dividend after 373, then repeat: 3733 / 603

Moving on to step 7:
The number 603 fits into 3733 6 times, leaving a remainder of 115.
The next digit of our result is 6. 
Result so far: 1866.0
Subtracting 3618 from 3733 leaves us with 115.
Include the next digit (8) from the dividend after 115, then repeat: 1158 / 603

Step 8:
603 goes into 1158 1 times with a remainder of 555.
Use 1 as the next digit of our solution. 
Result so far: 18661.0
Deduct 603 from 1158 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 9:
603 goes into 5550 9 times with a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 18661.9
The remainder is 123 after subtracting 5427 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 10:
1230 divided by 603 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 18661.92
If we subtract 1206 from 1230, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 603 fits into 240 0 times, leaving a remainder of 240.
The next digit of our result is 0. 
Result so far: 18661.92
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
The number 603 fits into 2400 3 times, leaving a remainder of 591.
Write down 3 as next digit of the result. 
Result so far: 18661.9203
Deduct 1809 from 2400 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Step 13:
The number 603 fits into 5910 9 times, leaving a remainder of 483.
The next digit of our result is 9. 
Result so far: 18661.92039
The remainder is 483 after subtracting 5427 from 5910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 14:
If we divide 4830 by 603, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18661.920398
Subtract 4824 from 4830 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
The number 603 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 18661.920398
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
600 divided by 603 is 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 18661.920398
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 18661.920398 with a remaining 6e-07.
