153115 ÷ 1 
We want to figure out the number of times 153115 can be divided by 1.

Going ahead to step 1:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Moving on to step 2:
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: 15.0
If we subtract 5 from 5, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Moving on to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 0 after subtracting 3 from 3.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Let's proceed to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1531.0
The remainder is 0 after subtracting 1 from 1.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 5:
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: 15311.0
Subtracting 1 from 1 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

On to step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 153115.0
Deduct 5 from 5 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.

Step 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 153115.0
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.

Let's proceed to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 153115.0
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.

The quotient of the division is 153115.0, and the remainder is 0.0.
