Let's divide 615603 by 75
We want to figure out the number of times 615603 can be divided by 75.

Going ahead to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 75

Moving on to step 2:
When dividing 61 by 75, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 75

Moving on to step 3:
75 can be fit into 615 8 times, resulting in a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 600 from 615 leaves us with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 75

Let's proceed to step 4:
75 goes into 156 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 82.0
The remainder is 6 after subtracting 150 from 156.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 75

Moving on to step 5:
When dividing 60 by 75, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 820.0
If we take 0 away from 60, we end up with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 75

On to step 6:
75 can be fit into 603 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8208.0
Subtracting 600 from 603 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 75, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8208.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 75 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 8208.04
Deduct 300 from 300 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8208.04
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8208.04
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8208.04 with a remainder of 0.0.
