We divide 748574 by 15
We want to divide 748574 by 15.

Step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 15

Let's proceed to step 2:
15 goes into 74 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 60 away from 74, we end up with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 15

Going ahead to step 3:
The number 15 fits into 148 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 135 from 148, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 15

Going ahead to step 4:
If we divide 135 by 15, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
Subtracting 135 from 135 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 15

Let's proceed to step 5:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 4990.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 15

Moving on to step 6:
15 can be fit into 74 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 49904.0
If we subtract 60 from 74, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
15 goes into 140 9 times with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 49904.9
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 49904.93
If we subtract 45 from 50, 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 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 49904.933
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 49904.933 with a remainder of 0.0005.
