We're dividing 7223015 by 915 
We want to divide 7223015 by 915.

Going ahead to step 1:
7 divided by 915 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 915

Let's proceed to step 2:
915 can be fit into 72 0 times, resulting in a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 915

Advancing to step 3:
If we divide 722 by 915, we get 0 and a remainder of 722.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 722 leaves us with 722.
Grab the next digit (3) from the dividend, add it to 722, then carry on: 7223 / 915

Let's proceed to step 4:
The number 915 fits into 7223 7 times, leaving a remainder of 818.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6405 from 7223 to get 818.
Fetch the next digit (0) from the dividend, attach it to 818 and continue: 8180 / 915

Step 5:
When dividing 8180 by 915, we get 8 with a remainder of 860.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 7320 from 8180 to get 860.
Bring next digit (1) of the dividend behind the 860 and repeat the process: 8601 / 915

Advancing to step 6:
When dividing 8601 by 915, we get 9 with a remainder of 366.
The number 9 becomes the next digit in our result. 
Result so far: 789.0
If we subtract 8235 from 8601, we get 366.
Append the next digit (5) from the dividend to 366 and continue with: 3665 / 915

Let's proceed to step 7:
The number 915 fits into 3665 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 7894.0
If we subtract 3660 from 3665, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
915 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7894.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 915, we get 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 7894.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 7894.0 and a remainder of 0.5.
