We look at the division of 491912 by 1 
Let's see how many times 1 fits into 491912.

Going ahead to step 1:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Going ahead to step 2:
When dividing 9 by 1, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 491.0
If we take 1 away from 1, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 4:
1 goes into 9 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4919.0
If we take 9 away from 9, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Advancing to step 5:
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: 49191.0
If we subtract 1 from 1, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Going ahead to step 6:
1 goes into 2 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 491912.0
If we take 2 away from 2, 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.

Step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 491912.0
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:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 491912.0
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.

In conclusion, the division gives 491912.0 with a balance of 0.0.
