Let's divide 721432 by 15
We want to divide 721432 by 15.

Going ahead to step 1:
7 divided by 15 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 15

Let's proceed to step 2:
If we divide 72 by 15, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 72 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 15

Step 3:
121 divided by 15 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 48.0
Deduct 120 from 121 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 15

Step 4:
15 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Subtract 0 from 14 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 15

Moving on to step 5:
The number 15 fits into 143 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 4809.0
Subtract 135 from 143 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 15

On to step 6:
15 goes into 82 5 times with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 48095.0
If we take 75 away from 82, 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.

Advancing to step 7:
70 divided by 15 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 48095.4
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 48095.46
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 48095.466
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 48095.466, with a leftover of 0.001.
