Let's divide 721244 by 15
Our goal is to divide 721244 by 15.

Let's proceed to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

On to step 2:
If we divide 72 by 15, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 60 away from 72, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 15

Step 3:
The number 15 fits into 121 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 120 from 121 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 15

Advancing to step 4:
15 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 480.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 15

Step 5:
If we divide 124 by 15, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 4808.0
Subtract 120 from 124 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 15

Moving on to step 6:
If we divide 44 by 15, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 48082.0
If we subtract 30 from 44, 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.

Moving on to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 48082.9
Subtract 135 from 140 to 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.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 48082.93
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.

Let's proceed to step 9:
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: 48082.933
Subtracting 45 from 50 leaves us 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 quotient of the division is 48082.933, and the remainder is 0.0005.
