624443 ÷ 20 
We want to figure out the number of times 624443 can be divided by 20.

Step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 20

Let's proceed to step 2:
If we divide 62 by 20, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 60 from 62 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 20

Advancing to step 3:
If we divide 24 by 20, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 20 from 24 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 20

Step 4:
The number 20 fits into 44 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 312.0
Deduct 40 from 44 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Step 5:
20 goes into 44 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 3122.0
The remainder is 4 after subtracting 40 from 44.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 20

Step 6:
When dividing 43 by 20, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 31222.0
If we take 40 away from 43, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 31222.1
If we subtract 20 from 30, 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:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 31222.15
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31222.15
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31222.15
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 31222.15 and a remainder of 0.0.
