We look at the division of 620605 by 2 
We want to divide 620605 by 2.

Moving on to step 1:
2 goes into 6 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Advancing to step 2:
When dividing 2 by 2, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Advancing to step 3:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
If we take 0 away from 0, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Advancing to step 4:
When dividing 6 by 2, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3103.0
If we take 6 away from 6, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Let's proceed to step 5:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31030.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Step 6:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 310302.0
The remainder is 1 after subtracting 4 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 310302.5
Deduct 10 from 10 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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 310302.5
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.

Step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 310302.5
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.

After the division, we end up with 310302.5 and a remainder of 0.0.
