We look at the division of 619519 by 1 
Let's see how many times 1 fits into 619519.

On to step 1:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Step 2:
1 divided by 1 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we take 1 away from 1, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Let's proceed to step 3:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 619.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 4:
5 divided by 1 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6195.0
The remainder is 0 after subtracting 5 from 5.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Going ahead to step 5:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 61951.0
If we subtract 1 from 1, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Going ahead to step 6:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 619519.0
Deduct 9 from 9 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.

Moving on to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 619519.0
If we subtract 0 from 0, 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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 619519.0
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.

In conclusion, the division gives 619519.0 with a balance of 0.0.
