We look at the division of 620470 by 20 
Our goal is to divide 620470 by 20.

Let's proceed to step 1:
6 divided by 20 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 20

Let's proceed to step 2:
20 goes into 62 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 62 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 20

Advancing to step 3:
The number 20 fits into 20 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 20 from 20, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 20

Step 4:
20 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 310.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 20

Advancing to step 5:
20 goes into 47 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 3102.0
If we subtract 40 from 47, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 20

Let's proceed to step 6:
When dividing 70 by 20, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 31023.0
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31023.5
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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31023.5
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31023.5
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.

The final outcome is 31023.5, with a leftover of 0.0.
