We're dividing 161565 by 1 
We want to figure out the number of times 161565 can be divided by 1.

Let's proceed to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 1 from 1 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Moving on to step 2:
When dividing 6 by 1, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 6 from 6, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 3:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 161.0
If we take 1 away from 1, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 4:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1615.0
If we take 5 away from 5, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

On to step 5:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 16156.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Going ahead to step 6:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 161565.0
The remainder is 0 after subtracting 5 from 5.
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:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 161565.0
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.

Let's proceed to step 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 161565.0
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 161565.0 with a balance of 0.0.
