We look at the division of 159122 by 1 
Our goal is to divide 159122 by 1.

Advancing to step 1:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing to step 2:
When dividing 5 by 1, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 9 from 9 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 4:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1591.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Moving on to step 5:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 15912.0
Subtract 2 from 2 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Moving on to step 6:
2 divided by 1 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 159122.0
If we subtract 2 from 2, 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.

Step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 159122.0
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.

Let's proceed to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 159122.0
If we take 0 away from 0, 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.

The final result is 159122.0 with a remainder of 0.0.
