We look at the division of 561612 by 1 
Our goal is to divide 561612 by 1.

Step 1:
5 divided by 1 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 6 from 6 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Going ahead to step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 561.0
Subtracting 1 from 1 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

On to step 4:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 5616.0
Subtract 6 from 6 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 56161.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Advancing to step 6:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 561612.0
Subtract 2 from 2 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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 561612.0
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.

Going ahead to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 561612.0
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 561612.0, with a leftover of 0.0.
