We look at the division of 603607 by 30 
We're looking to find how many times 30 goes into 603607.

Going ahead to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 30

Going ahead to step 2:
30 goes into 60 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 60 from 60, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 30

Moving on to step 3:
If we divide 3 by 30, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 30

Advancing to step 4:
When dividing 36 by 30, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 201.0
Subtracting 30 from 36 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 30

Advancing to step 5:
The number 30 fits into 60 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2012.0
Deduct 60 from 60 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 30

Let's proceed to step 6:
7 divided by 30 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 20120.0
Deduct 0 from 7 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 30 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 20120.2
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 20120.23
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 20120.233
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 20120.233, and the remainder is 0.001.
