Let's divide 621938 by 2
Let's see how many times 2 fits into 621938.

On to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Going ahead to step 2:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 2 from 2 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 3:
When dividing 1 by 2, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Step 4:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 3109.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Going ahead to step 5:
13 divided by 2 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 31096.0
Deduct 12 from 13 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Moving on to step 6:
2 goes into 18 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 310969.0
Subtract 18 from 18 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.

Going ahead to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 310969.0
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.

On to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 310969.0
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 310969.0, and the remainder is 0.0.
