We divide 619390 by 2
The aim is to understand the frequency of 2 in 619390.

Going ahead to step 1:
When dividing 6 by 2, we get 3 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 (1) from the dividend, add it to 0, then carry on: 1 / 2

On to step 2:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Let's proceed to step 3:
The number 2 fits into 19 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Subtract 18 from 19 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

Let's proceed to step 4:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 3096.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Going ahead to step 5:
If we divide 19 by 2, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 30969.0
Deduct 18 from 19 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Let's proceed to step 6:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 309695.0
If we subtract 10 from 10, we 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.

On to step 7:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 309695.0
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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 309695.0
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.

The final outcome is 309695.0, with a leftover of 0.0.
