We look at the division of 612909 by 1 
We're looking to find how many times 1 goes into 612909.

Going ahead to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Going ahead to step 2:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 61.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

On to step 3:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 612.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Step 4:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 6129.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 5:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 61290.0
If we subtract 0 from 0, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 6:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 612909.0
If we subtract 9 from 9, 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:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 612909.0
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.

Advancing to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 612909.0
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.

After the division, we end up with 612909.0 and a remainder of 0.0.
