We look at the division of 724664 by 20 
We want to divide 724664 by 20.

Moving on to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Let's proceed to step 2:
If we divide 72 by 20, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 12 after subtracting 60 from 72.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 20

Let's proceed to step 3:
20 can be fit into 124 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 120 from 124 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 20

Going ahead to step 4:
20 goes into 46 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 362.0
Subtract 40 from 46 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 20

Step 5:
20 can be fit into 66 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3623.0
Deduct 60 from 66 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 20

Going ahead to step 6:
20 can be fit into 64 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 36233.0
The remainder is 4 after subtracting 60 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 36233.2
Subtracting 40 from 40 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 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36233.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 36233.2
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.

Our division results in 36233.2 with a remaining 0.0.
