Let's divide 624736 by 20
Let's see how many times 20 fits into 624736.

Step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 20

On to step 2:
When dividing 62 by 20, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
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

Moving on to step 3:
When dividing 24 by 20, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 4 after subtracting 20 from 24.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 20

On to step 4:
47 divided by 20 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 312.0
Subtract 40 from 47 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 20

Let's proceed to step 5:
The number 20 fits into 73 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3123.0
If we take 60 away from 73, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 20

Let's proceed to step 6:
When dividing 136 by 20, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 31236.0
If we take 120 away from 136, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 31236.8
The remainder is 0 after subtracting 160 from 160.
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 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31236.8
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31236.8
If we take 0 away from 0, 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.

The quotient of the division is 31236.8, and the remainder is 0.0.
