We divide 603123 by 11
We want to divide 603123 by 11.

Moving on to step 1:
When dividing 6 by 11, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 11

Advancing to step 2:
60 divided by 11 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 5 after subtracting 55 from 60.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 11

On to step 3:
If we divide 53 by 11, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 9 after subtracting 44 from 53.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 11

Advancing to step 4:
11 goes into 91 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 548.0
Subtract 88 from 91 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 11

Advancing to step 5:
11 can be fit into 32 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 5482.0
Subtracting 22 from 32 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 11

Step 6:
103 divided by 11 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 54829.0
Subtracting 99 from 103 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
11 goes into 40 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 54829.3
Subtracting 33 from 40 leaves us 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.

Going ahead to step 8:
70 divided by 11 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 54829.36
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 54829.363
If we take 33 away from 40, we end up 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.

Going ahead to step 10:
11 goes into 70 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 54829.3636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
11 goes into 40 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 54829.36363
Deduct 33 from 40 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.

Going ahead to step 12:
When dividing 70 by 11, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 54829.363636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 11, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 54829.3636363
If we take 33 away from 40, we end up 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.

On to step 14:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 54829.36363636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 54829.36363636 and a remainder of 4e-09.
