Let's divide 151581 by 1
We want to divide 151581 by 1.

Going ahead to step 1:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Advancing to step 2:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 0 after subtracting 5 from 5.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Let's proceed to step 3:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 1 from 1 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Advancing to step 4:
If we divide 5 by 1, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1515.0
Subtract 5 from 5 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

On to step 5:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 15158.0
Subtract 8 from 8 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

On to step 6:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 151581.0
If we subtract 1 from 1, 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:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 151581.0
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.

Step 8:
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: 151581.0
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 quotient of the division is 151581.0, and the remainder is 0.0.
