724624 ÷ 20 
Our goal is to divide 724624 by 20.

Let's proceed to step 1:
7 divided by 20 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

On to step 2:
20 can be fit into 72 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 12 after subtracting 60 from 72.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 20

Going ahead to step 3:
When dividing 124 by 20, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 120 from 124 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Moving on to step 4:
If we divide 46 by 20, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 362.0
The remainder is 6 after subtracting 40 from 46.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 20

Moving on to step 5:
20 can be fit into 62 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3623.0
If we take 60 away from 62, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 20

Moving on to step 6:
When dividing 24 by 20, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 36231.0
If we subtract 20 from 24, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 36231.2
If we take 40 away from 40, we end up 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36231.2
Deduct 0 from 0 and we're left 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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36231.2
If we subtract 0 from 0, we 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.

Our division results in 36231.2 with a remaining 0.0.
